1Windows admin interview questions 1. Describe how the DHCP lease is obtained. It’s a four- step process consisting of (a) IP request, (b) IP offer, © IP selection and (d) acknowledgement. 2. I can’t seem to access the Internet, don’t have any access to the corporate network and on ipconfig my address is 169.254.*.*. What happened? The 169.254.*.* netmask is assigned to Windows machines running 98/2000/XP if the DHCP server is not available. The name for the technology is APIPA (Automatic Private Internet Protocol Addressing). 3. We’ve installed a new Windows-based DHCP server, however, the users do not seem to be getting DHCP leases off of it. The server must be authorized first with the Active Directory. 4. How can you force the client to give up the dhcp lease if you have access to the client PC? ipconfig /release 5. What authentication options do Windows 2000 Servers have for remote clients? PAP, SPAP, CHAP, MS-CHAP and EAP. 6. What are the networking protocol options for the Windows clients if for some reason you do not want to use TCP/IP? NWLink (Novell), NetBEUI, AppleTalk (Apple). 7. What is data link layer in the OSI reference model responsible for? Data link layer is located above the physical layer, but below the network layer. Taking raw data bits and packaging them into frames. The network layer will be responsible for addressing the frames, while the physical layer is reponsible for retrieving and sending raw data bits. 8. What is binding order? The order by which the network protocols are used for client-server communications. The most frequently used protocols should be at the top.

1Windows admin interview questions1. Describe how the DHCP lease is obtained. It’s a four-step process consisting of

(a) IP request, (b) IP offer, © IP selection and (d) acknowledgement. 2. I can’t seem to access the Internet, don’t have any access to the corporate

network and on ipconfig my address is 169.254.*.*. What happened? The 169.254.*.* netmask is assigned to Windows machines running 98/2000/XP if the DHCP server is not available. The name for the technology is APIPA (Automatic Private Internet Protocol Addressing).

3. We’ve installed a new Windows-based DHCP server, however, the users do not seem to be getting DHCP leases off of it. The server must be authorized first with the Active Directory.

4. How can you force the client to give up the dhcp lease if you have access to the client PC? ipconfig /release

5. What authentication options do Windows 2000 Servers have for remote clients? PAP, SPAP, CHAP, MS-CHAP and EAP.

6. What are the networking protocol options for the Windows clients if for some reason you do not want to use TCP/IP? NWLink (Novell), NetBEUI, AppleTalk (Apple).

7. What is data link layer in the OSI reference model responsible for? Data link layer is located above the physical layer, but below the network layer. Taking raw data bits and packaging them into frames. The network layer will be responsible for addressing the frames, while the physical layer is reponsible for retrieving and sending raw data bits.

8. What is binding order? The order by which the network protocols are used for client-server communications. The most frequently used protocols should be at the top.

9. How do cryptography-based keys ensure the validity of data transferred across the network?  Each IP packet is assigned a checksum, so if the checksums do not match on both receiving and transmitting ends, the data was modified or corrupted.

10. Should we deploy IPSEC-based security or certificate-based security? They are really two different technologies. IPSec secures the TCP/IP communication and protects the integrity of the packets. Certificate-based security ensures the validity of authenticated clients and servers.

11. What is LMHOSTS file? It’s a file stored on a host machine that is used to resolve NetBIOS to specific IP addresses.

12. What’s the difference between forward lookup and reverse lookup in DNS? Forward lookup is name-to-address, the reverse lookup is address-to-name.

13. How can you recover a file encrypted using EFS? Use the domain recovery agent.

what is diffrence between normal IDE disk and RAID disk ?

2. Nixon Says: October 8th, 2007 at 3:56 am

Hi,

How i can configured and troubleshoot DHCP server for mulipltle network and large domain environment

3. vijay Says: January 13th, 2008 at 3:05 am

hi

DHCP scope created for eight different network but DHCP Server is one of the network in the eight network. So DHCP server First will give the ip for its ownsubnet. then rest of the network it will not give the ip untill the request come form the different network. for that reason we need to active relay agent. here the relay agent is router. router is the bridge for the different network.

1Que.: What is Active Directory?

Ans. Active Directory is a Meta Data. Active Directory is a data base which store a data base like your user information, computer information and also other network object info. It has capabilities to manage and administor the complite Network which connect with AD.

2Que.: What is the Global Catalog?

Ans.: Global Catalog is a server which maintains the information about multiple domain with trust relationship agreement..

3Que: What is Active Directory?Ans: Active Directory directory service is an extensible and scalable directory service that enables you to manage network resources efficiently.

Q01: What is Active Directory?Ans:Active Directory is directory service that stores information about objects on a network and makes this information available to users and network administrators.Active Directory gives network users access to permitted resources anywhere on

Page 6: Windows Admin Interview Uestions

the network using a single logon process.It provides network administrators with an intuitive, hierarchical view of the network and a single point of administration3for all network objects.

5Q; What is active directory?

Ans: active directory is a domain controller which is use to authenticate and administrate the group of computer,user,server etc. remotely. all the policies and security will be applicable on the client machine which one is join the domain.and all this policies and security is defined in active directory.

2: What is LDAP?Ans2: LDAP(light weight directory accerss protocol) is an internet protocol which Email and other services is used to look up information from the server.

Q 18: What is KCC ?Ans 18: KCC ( knowledge consistency checker ) is used to generate replication topology for inter site replication and for intrasite replication.with in a site replication traffic is done via remote procedure calls over ip, while between site it is done through either RPC or SMTP.

Q 10: What is Global Catalog Server ?Ans 10 : Global Catalog Server is basically a container where you put the same type of member ,computer etc and applied the policies and security on the catalog server in place of individual user or computer.

Q; What is active directory?active directory is a domain controller which is use to authenticate and administrate the group of computer,user,server etc. remotely. all the policies and security will be applicable on the client machine which one is join the domain.and all this policies and security is defined in active directory.

Q 10 : what is Global catalog server GC?Ans : i m sorry i was given wrong ans of this question above but now im giving the exact ans of this question, and th ans which iwas given previously is the ans of Organisatinal Unit not of GC….. and the ans is

The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory forest. The global catalog is stored on domain controllers that have been designated as global catalog servers and is distributed through multimaster replication. Searches that are directed to the global catalog are faster because they do not involve referrals to different domain controllers.

Page 7: Windows Admin Interview Uestions

Q 4: Where is the AD database held? What other folders are related to AD?

A 4: The AD data base is store in NTDS.DIT.file

Q 5 :  What is the SYSVOL folder?A 5; The sysVOL folder stores the server’s copy of the domain’s public files. The contents such as group policy, users etc of the sysvol folder are replicated to all domain controllers in the domain.

Q 19: What is the ISTG? Who has that role by default?

A 19: Windows 2000 Domain controllers each create Active Directory Replication connection objects representing inbound replication from intra-site replication partners. For inter-site replication, one domain controller per site has the responsibility of evaluating the inter-site replication topology and creating Active Directory Replication Connection objects for appropriate bridgehead servers within its site. The domain controller in each site that owns this role is referred to as the Inter-Site Topology Generator (ISTG).

Q :15 What is LDP? What is REPLMON? What is ADSIEDIT? What is NETDOM? What is REPADMIN?A 15 : LDP : Label Distribution Protocol (LDP) is often used to establish MPLS LSPs when traffic engineering is not required. It establishes LSPs that follow the existing IP routing, and is particularly well suited for establishing a full mesh of LSPs between all of the routers on the network.Replmon : Replmon displays information about Active Directory Replication.ADSIEDIT :ADSIEdit is a Microsoft Management Console (MMC) snap-in that acts as a low-level editor for Active Directory. It is a Graphical User Interface (GUI) tool. Network administrators can use it for common administrative tasks such as adding, deleting, and moving objects with a directory service. The attributes for each object can be edited or deleted by using this tool. ADSIEdit uses the ADSI application programming interfaces (APIs) to access Active Directory. The following are the required files for using this tool: ADSIEDIT.DLLADSIEDIT.MSCNETDOM : NETDOM is a command-line tool that allows management of Windows domains and trust relationships. It is used for batch management of trusts, joining computers to domains, verifying trusts, and secure channels.

REPADMIN :This command-line tool assists administrators in diagnosing replication problems between Windows domain controllers.Administrators can use Repadmin to view the replication topology (sometimes referred to as RepsFrom and RepsTo) as seen

Page 8: Windows Admin Interview Uestions

from the perspective of each domain controller. In addition, Repadmin can be used to manually create the replication topology (although in normal practice this should not be necessary), to force replication events between domain controllers, and to view both the replication metadata and up-to-dateness vectors.

Q 36: how to take backup of AD ?A 36 : for taking backup of active directory you have to do this :first go to START -> PROGRAM ->ACCESORIES -> SYSTEM TOOLS -> BACKUPwhen the backup screen is flash then take the backup of SYSTEM STATE it will take the backup of all the necessary information about the syatem including AD backup , DNS ETC.

Q 37 : how to restore the AD  ?a 37 : For ths do the same as above in the question 36 but in place of backup you select the restore option and restore the system state .

Q 19: What is the ISTG? Who has that role by default?A 19: Inter-Site Topology Generator(istg)  is responsible for managing the inbound replication connection objects for all bridgehead servers in the site in which it is located. This domain controller is known as the Inter-Site Topology Generator (ISTG). The domain controller holding this role may not necessarily also be a bridgehead server.

Q 29 :What are the DS* commands A 29 : You really are spoilt for choice when it comes to scripting tools for creating Active Directory objects.  In addition to CSVDE, LDIFDE and VBScript, we now have the following DS commands: the da family built in utility DSmod - modify Active Directory attributesDSrm - to delete Active Directory objectsDSmove - to relocate objectsDSadd - create new accounts DSquery - to find objects that match your query attributes DSget - list the properties of an object

Q 30 :What’s the difference between LDIFDE and CSVDE? Usage considerations?A 30 : CSVDE is a command that can be used to import and export objects to and from the AD into a CSV-formatted file. A CSV (Comma Separated Value) file is a file easily readable in Excel. I will not go to length into this powerful command, but I will show you some basic samples of how to import a large number of users into your AD. Of course, as with the DSADD command, CSVDE can do more than just import users. Consult your help file for more info.Like CSVDE, LDIFDE is a command that can be used to import and export objects to and from the AD into a LDIF-formatted file. A LDIF (LDAP Data Interchange Format) file is a file easily readable in any text editor, however it is not readable in programs like Excel. The major difference between CSVDE and LDIFDE (besides the file format) is the fact that LDIFDE can be used to edit and

Page 9: Windows Admin Interview Uestions

delete existing AD objects (not just users), while CSVDE can only import and export objects.

Q 25 : What is tombstone lifetime attribute?

A 25 : The number of days before a deleted object is removed from the directory services. This assists in removing objects from replicated servers and preventing restores from reintroducing a deleted object. This value is in the Directory Service object in the configuration NIC.

You want to standardize the desktop environments (wallpaper, My Documents, Start menu, printers etc.) on the computers in one department. How would you do that? How it is possibal

(20)What are the requirements for installing AD on a new server?Ans:1)The Domain structure2)The Domain Name3)storage location of the database and log file4)Location of the shared system volume folder5)DNS config Methode6)DNS configuration

7. What are application partitions? When do I use them.

Ans: AN application diretcory partition is a directory partition that is replicated only to specific domain controller.Only domain controller running windows Server 2003 can host a replica of application directory partition.

Using an application directory partition provides redundany,availabiltiy or fault tolerance by replicating data to specific domain controller pr any set of domain controllers anywhere in the forest

Q:You want to standardize the desktop environments (wallpaper, My Documents, Start menu, printers etc.) on the computers in one department. How would you do that? How it is possibal.

Ans:Login on client as Domain Admin user change whatever you need add printers etc go to system-User profiles copy this user profile to any location by select Everyone in permitted to use after copy change ntuser.dat to ntuser.man and assgin this path under user profile

Q. 8. How do you create a new application partition

ANS:Use the DnsCmd command to create an application directory partition. To do this, use the following syntax:DnsCmd ServerName /CreateDirectoryPartition FQDN of partition

Page 10: Windows Admin Interview Uestions

Global catalog provides a central repository of domain information for the forest by storing partial replicas of all domain directory partitions. These partial replicas are distributed by multimaster replication to all global catalog servers in a forest.Its also used in universal global membership.

How do you view all the GCs in the forest?

AnsC:\>repadmin /showrepsdomain_controllerwhere domain_controller is the DC you want to query to determine whether it’s a GC. The output will include the text DSA Options: IS_GC if the DC is a GC. . . .

Trying to look at the Schema, how can I do that

Ans:type “adsiedit.msc” in run or command prompt

Q. Can you connect Active Directory to other 3rd-party Directory Services? Name a few options.

Ans. Yes, you can use dirXML or LDAP to connect to other directories

In Novell you can use E-directory

Q 38 :How do you change the DS Restore admin password ?

Ans 38: A. In Windows 2000 Server, you used to have to boot the computer whose password you wanted to change in Directory Restore mode, then use either the Microsoft Management Console (MMC) Local User and Groups snap-in or the commandnet user administrator *to change the Administrator password. Win2K Server Service Pack 2 (SP2) introduced the Setpwd utility, which lets you reset the Directory Service Restore Mode password without having to reboot the computer. (Microsoft refreshed Setpwd in SP4 to improve the utility’s scripting options.)In Windows Server 2003, you use the Ntdsutil utility to modify the Directory Service Restore Mode Administrator password. To do so, follow these steps:1. Start Ntdsutil (click Start, Run; enter cmd.exe; then enter ntdsutil.exe).2. Start the Directory Service Restore Mode Administrator password-reset utility by entering the argument “set dsrm password” at the ntdsutil prompt:ntdsutil: set dsrm password3. Run the Reset Password command, passing the name of the server on which to change the password, or use the null argument to specify the local machine. For example, to reset the password on server thanos, enter the following argument at the Reset DSRM Administrator Password prompt:

Page 11: Windows Admin Interview Uestions

Reset DSRM Administrator Password: reset password on server thanosTo reset the password on the local machine, specify null as the server name:Reset DSRM Administrator Password: reset password on server null4. You’ll be prompted twice to enter the new password. You’ll see the following messages:5. Please type password for DS Restore Mode Administrator Account:6. Please confirm new password:Password has been set successfully.7. Exit the password-reset utility by typing “quit” at the following prompts:8. Reset DSRM Administrator Password: quitntdsutil: quit

Q.40: What are Group Policy objects (GPOs)?A.40: Group Policy objects, other than the local Group Policy object, are virtual objects. The policy setting information of a GPO is actually stored in two locations: the Group Policy container and the Group Policy template. The Group Policy container is an Active Directory container that stores GPO properties, including information on version, GPO status, and a list of components that have settings in the GPO. The Group Policy template is a folder structure within the file system that stores Administrative Template-based policies, security settings, script files, and information regarding applications that are available for Group Policy Software Installation. The Group Policy template is located in the system volume folder (Sysvol) in the \Policies subfolder for its domain.

Q) i have been asked if there is set of 30 harddisk configured for raid 5 if two harddisk failed what about dataA) It depends how u had configured ur RAID its only Raid5 or with with spare if its only raid 5 then in raid5 if ur 2 nos of HDD goes then ur raid is gone.

Q) How Can i Deploy the Latest Patched in Pc through G.P. wihtout having the Admin Right in Pc.

Page 13: Windows Admin Interview Uestions

A) Create a batch file and place all the patches in the Netlogon, and deploy the batch file through GP to all the pcs so the same should take affect after restarting the pc.

Q) In Raid 5,Suppose i have 5 HDD of 10-10 GB, After configuring the Raid how much space do i have for utilise.A) -1 out of the total (eg- if u r using 5 u will get only 4 because 1 goes for parity).

Q) How Can i Resolve the Svr name through NslookupA) what exactly u want to do, nslookup command will let u know through which server u r getting routed, (eg- c:\nslookup then u will get ur domain name to which u r getting routed. and if u want to get the name of the pc/server with the ip address then u have to give the command c:\nbtstat -a ip xx-xx-xx-xx)

Q)How Can i Deploy the Latest Patched in Pc through G.P. wihtout having the Admin Right in Pc.A) Create a batch file and place all the patches in the Netlogon, and deploy the batch file through GP to all the pcs so the same should take affect after restarting the pc.the answer to the above question is incorrect.you cannot deploy a batch file using group policy.you can only publish or assign msi packages or Zap files. They are the only two valid file formats allowable when using “intellimirror”. in active directory.

***TELL ME WHY WE R USEING EXCHANGE SERVER?

Page 15: Windows Admin Interview Uestions

This is a mail server.. we can use this Server to send mails in Intranet as well as outside.

*** What is DHCP?

To assign ip addresses automatically.

*** DHCP relay agent where to place it?

DHCP Relay agent u need to place in Software Router.

*** what is forest?

Is a collection of trees. Tree is nothing but collection domains which is having same name space.domain contains domain controllers..forest — Tree — Domain –

Don’t get confused.. Understand carefully.

*** what is GC? how many required for A Tree?

Global Catalog server is a Searchable Index book. With this we can find out any object in the Active Directory.

Also it works as logon authentication for Group memberships.

We can have each domain controller in domain or only first domain controller in a domain..

*** DNS zones, chronicle records what are they?

In Windows 2000 there are mainly 3 zones

QHow Can i Deploy the Latest Patched in Pc through G.P. wihtout having the Admin Right in Pc.A) Create a batch file and place all the patches in the Netlogon, and deploy the batch file through GP to all the pcs so the same should take affect after restarting the pc.

the answer to the above question is incorrect.

you cannot deploy a batch file using group policy.

you can only publish or assign msi packages or Zap files. They are the only two valid file formats allowable when using “intellimirror”. in active directory.

Page 19: Windows Admin Interview Uestions

Actually you are incorrect as well. If you create a script and assign it to the STARTUP script in a GPO applied to the COMPUTER and not the USER, then it runs as a local administrator on the computer.

QWhat is difference between scope and superscope ?

Scope in dhcp, where u can specify a range of IP Address which will be leased to the dhcp clients.Superscope is the combination of multiple scopes.

QDescribe the lease process of the DHCP server.

DHCP Server leases the IP addresses to the clients as follows :DORAD (Discover) : DHCP Client sends a broadcast packets to identify the dhcp server, this packet will contain the source MAC.O (Offer) : Once the packet is recieved by the DHCP server, the server will send the packet containing Source IP and Source MAC.R (Request) : Client will now contact the DHCP server directly and request for the IP address.A (Acknowledge) : DHCP server will send an ack packet which contains the IP address.The default lease period is 8 days.

QWhat is the new major feature introduced in Exchange 2003, which was not included in Exchange 2000?

QWhat is a smarthost?

A Exchange server is having bandwidth issues, explain how you would look at fixing the issue?

QWhat is Blue Screen Error? and when it comes?What is clean Booting?What is warm and cold booting?Difference between clean Boot and safe mode?

QWhat is warm and cold booting?

ans:A warm boot, accomplished by pressing the CTRL+ALT+DEL key combination, restarts the computer through the INT19h ROM BIOS routine. This warm-boot procedure usually does not go through the complete boot process; generally, it skips the power-on self test (POST) to save time. In addition, a warm boot frequently fails to reset all adapters in the computer’s adapter slots.

If you use the Reset button to cold boot the computer, it generally restarts the boot process, including the POST. However, this procedure does not necessarily discontinue power to the motherboard. If the power is not interrupted, the cold boot may fail to reset all adapters in the computer’s adapter slots.

if u want any other clarification let me know

QWhat is Active Directory?

Active Directory is a stored collection of information about objects that are related to each other. It provides the means to organize and simplify access to resources of a networked environment.

QWhat is LDAP?

LDAP is a worldwide IETF standard protocol, it is designed to allow for the transfer of information between domain controllers and to allow users to query information about objects within directory.

Difference in Windows server2000 and 2003?

5) Stupid Interview   Questions · Wed May 17, 12:38 PM

I was reading a blog post on some guy’s programming interview, where he complained about being asked to write a file copy function. Now, while it’s quite possible to take umbrage at this, if I were in that situation, I’d see it as a chance for some free entertainment .

Q. What do you mean by “copy”?A. Ummm…copy the contents of the file to a new file.Q. What about the date/time stamps?A. No, those don’t need to be copied.Q. Does the result file have to have the same name?A. No.Q. Can it have the same name?A. Umm…no.Q. Do I have to worry about name spoofing? What about the Turkish I?A. Don’t worry about that.Q. Does it have to be in the same location? Note that if it is in the same location, it (probably) can’t have the same name. Unless you copy it to itself (another question…).A. Yes.Q. What about the attributes?A. Make the attributes the same.Q. Should I modify the attributes of the source file? If this file copy is part of a backup or archive operation, it’d probably be a mistake to leave the ‘Archive’ attribute on.A. No, leave them as-is.Q. What if the source file has the Archive attribute off? If I make it off on the new file as well, it could screw up the user’s backup software.A. Just make it the same. I don’t care about the user’s backup software.Q. Well, I’m not sure that’s the best approach to take when thinking about designing software FOR users, but if you say so.A. ...Q. What about compression? It’s a file attribute, but the copy destination may not support compression.A. Don’t compress the copy.Q. Even if the source is compressed, and the destination supports compression?

Page 23: Windows Admin Interview Uestions

A. YES.Q. What about encryption? What if the source file is encrypted, but the destination does not support encryption?A. Don’t encrypt the copy if the destination doesn’t support it.Q. Mmmmm, sorry, don’t mean to digress, but…that could be a serious security hole. Especially if wherever this file copy function ends up supports arbitrary parameters (directly or indirectly).A. Look, just copy the damn file.Q. What about the file creator?A. Don’t care.Q. What about the file owner?A. Don’t care.Q. What about file permissions? Is there a separate way we should handle inherited permissions and assigned permissions?A. Forget the permissions.Q. What operating system will this function be required to run on?A. Windows XP.Q. Home, or Pro, or Media Center, or one or more?A. Pro.Q. What service pack level are we aiming for?A. Service Pack 2.Q. Does that mean we don’t have to support any other SP level?A. Yes, fine.Q. How will the source file name be supplied?A. As a parameter.Q. Is it going to be supplied as a null-terminated string, a counted string, or an object?A. Null-terminated string.Q. Is it possible that a NULL pointer will be passed in?A. No.Q. Is it possible that an empty string will be passed in?A. No.Q. Is it possible that a malformed string will be passed in (e.g., no NULL terminator)?A. No.Q. What encoding will the filename be in?A. Unicode.Q. Sorry, umm…Unicode is not an encoding, really. If we’re using Unicode data, it has to have a specific encoding, like UTF-8, UCS-2, UTF-16, etc.A. Fine. Make it UTF-8.Q. OK. I’d like to note at this point that it’s a bit of a pain to have to transcode UTF-8 to UTF-16 in order to be able to supply it to Windows API calls.A. Fine! UTF-16!Q. Big-endian or little-endian?

Page 24: Windows Admin Interview Uestions

A. ARGH. Whichever you want!Q. Should we accept relative paths, or only fully-specified paths?A. Only full paths.Q. Are there any characteristics of the paths we are supposed to accept that I can screen the parameters on?A. No. The caller will do all screening of paths and file names.Q. How will the destination file name be generated or supplied
