1Windows admin interview questions

1. Describe how the DHCP lease is obtained. Its a four-step process consisting of(a) IP request, (b) IP offer, IP selection and (d) acknowledgement.

2. I cant seem to access the Internet, dont have any access to the corporatenetwork and on ipconfig my address is 169.254.*.*. What happened? The169.254.*.* netmask is assigned to Windows machines running 98/2000/XP if theDHCP server is not available. The name for the technology is APIPA (AutomaticPrivate Internet Protocol Addressing).

3. Weve installed a new Windows-based DHCP server, however, the users donot seem to be getting DHCP leases off of it. The server must be authorized firstwith the Active Directory.

4. How can you force the client to give up the dhcp lease if you have access tothe 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 somereason 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 linklayer is located above the physical layer, but below the network layer. Takingraw data bits and packaging them into frames. The network layer will beresponsible for addressing the frames, while the physical layer is reponsible forretrieving and sending raw data bits.

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

the top.9. How do cryptography-based keys ensure the validity of data transferredacross the network? Each IP packet is assigned a checksum, so if the checksumsdo not match on both receiving and transmitting ends, the data was modified orcorrupted.

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

11. What is LMHOSTS file? Its a file stored on a host machine that is used toresolve NetBIOS to specific IP addresses.

12. Whats 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 recoveryagent.

Question:I have 8 different and 8 difernet DHCP scope for every network ,i meanfor every subnets,but ,when all the subnet starting at one time ,i want to make the2nd subnet work withthe high prority,i mean the 2nd sunet should get teh IPaddressfrom the DHCP server first?How is it possible?

please mail me bak.



I have a printer (dhcp enabled) . there are 2 dhcp servers both are running . Whenthe printer is switched on Which DHCP server will it get the ip from .Can it be configured to always use one specific DHCP server

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 andlarge 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 thenetwork 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 formthe different network. for that reason we need to active relay agent. here the relayagent 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 storea data base like your user information, computer information and also othernetwork object info. It has capabilities to manage and administor the compliteNetwork which connect with AD.

2Que.: What is the Global Catalog?

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

3Que: What is Active Directory?

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

Q01: What is Active Directory?

Ans:Active Directory is directory service that stores information about objects ona network and makes this information available to users and networkadministrators.Active Directory gives network users access to permitted resources anywhere onthe 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 andadministrate the group of computer,user,server etc. remotely. all the policies andsecurity will be applicable on the client machine which one is join the domain.andall this policies and security is defined in active directory.

2: What is LDAP?Ans2: LDAP(light weight directory accerss protocol) is an internet protocol whichEmail 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 sitereplication traffic is done via remote procedure calls over ip, while between site itis 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 sametype of member ,computer etc and applied the policies and security on the catalogserver 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 andsecurity will be applicable on the client machine which one is join the domain.andall 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 givingthe exact ans of this question, and th ans which iwas given previously is the ans ofOrganisatinal 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 ActiveDirectory forest. The global catalog is stored on domain controllers that have beendesignated as global catalog servers and is distributed through multimasterreplication. Searches that are directed to the global catalog are faster because theydo not involve referrals to different domain controllers.

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


7/24

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 servers copy of the domains public files. The

contents such as group policy, users etc of the sysvol folder are replicated to alldomain 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 Replicationconnection objects representing inbound replication from intra-site replicationpartners. For inter-site replication, one domain controller per site has theresponsibility of evaluating the inter-site replication topology and creating Active

Directory Replication Connection objects for appropriate bridgehead serverswithin its site. The domain controller in each site that owns this role is referred toas the Inter-Site Topology Generator (ISTG).

Q :15 What is LDP? What is REPLMON? What is ADSIEDIT? What isNETDOM? What is REPADMIN?A 15 : LDP : Label Distribution Protocol (LDP) is often used to establish MPLSLSPs when traffic engineering is not required. It establishes LSPs that follow theexisting IP routing, and is particularly well suited for establishing a full mesh ofLSPs 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 thatacts as a low-level editor for Active Directory. It is a Graphical User Interface(GUI) tool. Network administrators can use it for common administrative taskssuch as adding, deleting, and moving objects with a directory service. Theattributes for each object can be edited or deleted by using this tool. ADSIEdituses the ADSI application programming interfaces (APIs) to access ActiveDirectory. The following are the required files for using this tool: ADSIEDIT.DLLADSIEDIT.MSCNETDOM : NETDOM is a command-line tool that allowsmanagement of Windows domains and trust relationships. It is used for batchmanagement of trusts, joining computers to domains, verifying trusts, and securechannels.

REPADMIN :This command-line tool assists administrators in diagnosing replication problemsbetween Windows domain controllers.Administrators can use Repadmin to viewthe replication topology (sometimes referred to as RepsFrom and RepsTo) as seenfrom the perspective of each domain controller. In addition, Repadmin can beused to manually create the replication topology (although in normal practice this


8/24

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 willtake the backup of all the necessary information about the syatem including ADbackup , 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 youselect 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 theinbound replication connection objects for all bridgehead servers in the site inwhich it is located. This domain controller is known as the Inter-Site TopologyGenerator (ISTG). The domain controller holding this role may not necessarilyalso be a bridgehead server.

Q 29 :What are the DS* commands A 29 : You really are spoilt for choice when itcomes to scripting tools for creating Active Directory objects. In addition toCSVDE, LDIFDE and VBScript, we now have the following DS commands: theda family built in utility DSmod - modify Active Directory attributesDSrm - todelete Active Directory objectsDSmove - to relocate objectsDSadd - create new

accountsDSquery - to find objects that match your query attributesDSget - list theproperties of an object

Q 30 :Whats the difference between LDIFDE and CSVDE? Usageconsiderations?A 30 : CSVDE is a command that can be used to import and export objects to andfrom the AD into a CSV-formatted file. A CSV (Comma Separated Value) file is afile 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 usersinto your AD. Of course, as with the DSADD command, CSVDE can do morethan just import users. Consult your help file for more info.Like CSVDE, LDIFDE is a command that can be used to import and exportobjects to and from the AD into a LDIF-formatted file. A LDIF (LDAP DataInterchange Format) file is a file easily readable in any text editor, however it isnot readable in programs like Excel. The major difference between CSVDE andLDIFDE (besides the file format) is the fact that LDIFDE can be used to edit anddelete existing AD objects (not just users), while CSVDE can only import andexport objects.

9/24

Q 25 : What is tombstone lifetime attribute?

A 25 : The number of days before a deleted object is removed from the directoryservices. This assists in removing objects from replicated servers and preventingrestores 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 dothat? 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 thedatabase and log file4)Location of the shared system volume folder5)DNS configMethode6)DNS configuration

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

Ans: AN application diretcory partition is a directory partition that is replicatedonly to specific domain controller.Only domain controller running windowsServer 2003 can host a replica of application directory partition.

Using an application directory partition provides redundany,availabiltiy or faulttolerance by replicating data to specific domain controller pr any set of domaincontrollers 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 dothat? How it is possibal.

Ans:Login on client as Domain Admin user change whatever you need addprinters etc go to system-User profiles copy this user profile to any location byselect Everyone in permitted to use after copy change ntuser.dat to ntuser.man andassgin 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

Global catalog provides a central repository of domain information for the forestby storing partial replicas of all domain directory partitions. These partial replicas


10/24

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 its aGC. 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? Namea 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 computerwhose password you wanted to change in Directory Restore mode, then use either

the Microsoft Management Console (MMC) Local User and Groups snap-in orthe 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 RestoreMode password without having to reboot the computer. (Microsoft refreshedSetpwd in SP4 to improve the utilitys scripting options.)In Windows Server 2003, you use the Ntdsutil utility to modify the DirectoryService 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 tochange the password, or use the null argument to specify the local machine. Forexample, to reset the password on server thanos, enter the following argument atthe Reset DSRM Administrator Password prompt:Reset DSRM Administrator Password: reset password on server thanosTo reset the password on the local machine, specify null as the server name:


11/24

Reset DSRM Administrator Password: reset password on server null4. Youll be prompted twice to enter the new password. Youll see the followingmessages: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 virtualobjects. The policy setting information of a GPO is actually stored in twolocations: the Group Policy container and the Group Policy template. The GroupPolicy 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 thefile system that stores Administrative Template-based policies, security settings,script files, and information regarding applications that are available for GroupPolicy Software Installation. The Group Policy template is located in the systemvolume folder (Sysvol) in the \Policies subfolder for its domain.

QHow Can i Deploy the Latest Patched in Pc through G.P. wihtout having theAdmin Right in Pc.A) Create a batch file and place all the patches in the Netlogon, and deploy thebatch file through GP to all the pcs so the same should take affect after restartingthe 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 twovalid file formats allowable when using intellimirror. in active directory.

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

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. Thiswarm-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 warmboot frequently fails to reset all adapters in the computers adapter slots.

If you use the Reset button to cold boot the computer, it generally restarts the bootprocess, including the POST. However, this procedure does not necessarilydiscontinue power to the motherboard. If the power is not interrupted, the coldboot may fail to reset all adapters in the computers adapter slots.

if u want any other clarification let me know

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

I was reading a blog post on some guys programming interview,

where he complained about being asked to write a file copy function.Now, while its quite possible to take umbrage at this, ifI were inthat situation, Id see it as a chance for some free entertainment .

Q. What do you mean by copy?

A. Ummmcopy the contents of the file to a new file.Q. What about the date/time stamps?

A. No, those dont 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. Ummno.Q. Do I have to worry about name spoofing? What about the Turkish

I?A. Dont worry about that.

Q. Does it have to be in the same location? Note that if it is in thesame location, it (probably) cant 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 ispart of a backup or archive operation, itd probably be a mistake toleave the Archive attribute on.

A. No, leave them as-is.

Q. What if the source file has the Archive attribute off? If I make itoff on the new file as well, it could screw up the users backup

software.A. Just make it the same. I dont care about the users backup

software.

Q. Well, Im not sure thats the best approach to take when thinkingabout designing software FOR users, but if you say so.

A. ...Q. What about compression? Its a file attribute, but the copy

destination may not support compression.

A. Dont compress the copy.Q. Even if the source is compressed, and the destination supports

compression?A. YES.

23/24

Q. What about encryption? What if the source file is encrypted, butthe destination does not support encryption?

A. Dont encrypt the copy if the destination doesnt support it.Q. Mmmmm, sorry, dont mean to digress, butthat 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. Dont care.

Q. What about the file owner?

A. Dont 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 dont 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 countedstring, 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, ummUnicode is not an encoding, really. If were usingUnicode data, it has to have a specific encoding, like UTF-8, UCS-2,UTF-16, etc.

A. Fine. Make it UTF-8.Q. OK. Id like to note at this point that its a bit of a pain to have to

transcode UTF-8 to UTF-16 in order to be able to supply it toWindows API calls.

A. Fine! UTF-16!


24/24

Q. Big-endian or little-endian?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
