What Is DHCP What Is DHCP - Dynamic Host Configuration Protocol servers assign IP addressesstatically or dynamically dependant upon DHCP configuration and network ...

DHCP Server DHCP Server alots the IP addresses to computers, while DNS server resolves them.You need DHCP Server if you do not want to manually maintain IP Addresses ...

Definition for safe mode: Safe mode is a diagnostic mode of a computer operating system (OS). It can alsorefer to a mode of operation by application software. Safe mode is intended to fixmost, if not all problems within an operating system..

What is safe mode?

Safe mode is a troubleshooting option for Windows that starts your computer in a

limited state. Only the basic files and drivers necessary to run Windows are started.

The words "Safe Mode" appear in the corners of the display to identify

which Windows mode you are using. If an existing problem does not reappear when

you start in safe mode, you can eliminate the default settings and basic device

drivers as possible causes.

If your computer automatically starts in safe mode without prompting, a problemwith your computer might be preventing Windows from starting normally. If you

think the cause of the problem might be a recently installed program or device, try

using System Restore. For more information, see What is System Restore?

Microsoft Windows Vista and Windows 7 users

If you are running Safe Mode because you cannot get intoWindows, you may want to first try loading the last known goodconfiguration.

To get into the Windows Vista and Windows 7 Safe Mode, as thecomputer is booting press and hold your "F8 Key" which should bringup the "Windows Advanced Options Menu" as shown below. Use

your arrow keys to move to "Safe Mode" and press your Enter key.

Note: With some computers if you press and hold a key as the

computer is booting you will get a stuck key message. If this occurs,



instead of pressing and holding the "F8 key", tap the "F8 key"continuously until you get the startup menu.

Trouble Getting into Safe mode - If after several attempts you areunable to get into Safe Mode as the computer is booting into

Windows, turn off your computer. When the computer is turned onthe next time Windows should notice that the computer did not

Reason

If you cannot boot into normal Windows mode or cannot

troubleshoot because of errors in normal mode boot into SafeMode. Windows Safe Mode bypasses startup programs and driversthat are not required for Windows to load and will allow you to fixWindows problems

OUT LOOKNOTES

Outlook Express is part of Internet Explorer and comes with every version of Windows.Depending on what version of Internet Explorer you have will determine what version of

Outlook Express you have. For example, IE 6 will have Outlook Express 6.

Outlook itself is a more powerful version of Outlook Express and is separate from InternetExplorer. It can be purchased by itself or it can also come included with Microsoft Office.

Here are some of the features of Outlook that Outlook Express does not have:

y Capability to connect to a Microsoft Exchange Server for e -mail other than internet e -mail.

y Built in Task and Contact management capabilitiesy Calendar y E-mail filtering and rulesy Sharing of public folders, forms, scheduling etc. with Exchange Server users

y Integration with Microsoft Office

For most home users Outlook Express will do the job. You can have multiple e -mailaccounts setup and keep an address book of your contacts. If you are in a work environmentand need to connect to an Exchange Server to share information with co -workers the

Outlook is your best bet.

What is the difference between Microsoft Outlook and

Microsoft Outlook Express?

Basics of Outlook Express

Outlook Express is a POP3- and IMAP-compatible mail client with a built -in

newsreader. It is available with Internet Explorer for Windows XP. Outlook Express is

much simpler to set up and use if you only need to read email messages and access



newsgroups. You can configure it to retrieve email messages from your account via

POP or configure it as an IMAP client to access your mail on an IMAP mail server.

Note: UITS no longer supports POP mail. For details, see At IU, why doesn't UITS

support POP mail?

To set up Outlook Express to read your email at IU, follow the appropriate

instructions:

y At IU, how do I configure Outlook Express for Windows to read my mail on the Cyrus

mail system?

y At IU, in Outlook Express for Windows, how do I read my Exchange mail using

IMAP?

Basics of Outlook

Outlook is also an email client, but unlike Outlook Express, it is also a personal

information manager. You can use it for viewing and maintaining calendars,

organizing contacts, and managing tasks. When you use it with an IU Exchange

server account, you can use it for group scheduling and sharing your contacts and

tasks with others.

To set up Outlook to read your email at IU, follow the appropriate instructions:

y At IU, using Outlook 2010 or 2007, how do I access my Exchange mailbox?

y At IU, in Outlook 2003, how do I access my Exchange mailbox?

y At IU, in Outlook, how do I read my Cyrus or Exchange email using IMAP?

Both Outlook and Outlook Express can receive email from multiple accounts.

VPN Ports: Your Entry and ExitThe network port refers to the number assigned to each message. The standard network portals

like TCP, IP, UDP usually attaches port number to the data it sends. The type of service provided

is based on this port number. This assignment is usually based on logic. Learn more about

hardware and software VPN ports. Simply read on. The article covers

IP Addresses

Software ports

The network port is usually number and standard network protocols l ike TCP, IP, UDP attaches a

port number to the data it sends. A port number is to be assigned to each message according to

the TCP layer requirements. This port (logical reference) number determines the type of service



provided. This software network port (address in the form of a number) is assigned to a service

for communicating between a program and another program/communication system. This

naming system is logical and pertains to the services that carry on long term conversation. A list

that specifies the port used by the server process is known as its contact port. A service contact

port is defined to provide specific service to unknown callers. These software network ports also

connect internal programs on the same computer. Numbers from 0 to 1023 are used to identify a

network service on the internet (Internet Protocol). Each IP packet contains a TCP or UDP

header which directs applications to the appropriate application in the server. Reserved port

numbers and unassigned numbers can be used by application programs.

The Internet Assigned Numbers Authority (IANA) registers ports 1024 to 49151 for the

convenience of internet continuity. Port numbers from 49151 to 65535 are called dynamic ports

and are private. You could look up IANA for more details on assigned port numbers. The most

well-known port is 80, which identifies HTTP traffic for a Web server. The Well Known Ports are

assigned by the IANA and on most systems can only be used by system (or root) processes or

by programs executed by privileged users. Port numbers are straight unsigned integer values

which range up to a value of 65535. Below is a list of well known ports and their services.

IP Addresses TCP/IP stands for Transmission Control Protocol and IP for Internet Protocol. These protocols

are responsible for transporting and managing the data across the network. The IPv4 requires a

4 byte address to be assigned to each network interface card that exists on all the computers in

the network where as the Ipv6 assigns a 6 byte address. IP Addresses works almost like a house

address without which determining where data packets go would be impossible. This assignment

of address can be done automatically by network software's such as the DHCP which is the

dynamic host configuration protocol or by manually entering static addresses into the computer.

The part of the IP address that defines the network is the network ID, and the latter part of the IPaddress defining the host address is the host ID.

Using this port and addressing scheme, the networking system can pass data, addressing

information, and type of service information through the hardware, from one computer to another.
