Telnet
Telnet is a simple, text-based program that lets you connect to another computer via the Internet. If
you've been granted the right to connect to that computer by that computer's owner or administrator,
Telnet will let you enter commands used to access programs and services that are on the remote
computer, as if you were sitting right in front of it.
The Telnet command prompt tool is included with the Windows Server 2003 and Windows XP operating
systems. See the related OS documentation and helps for more information. Note that if you are only
using computers running Windows, it may be easier to use the Windows Remote Desktop feature. For
more information about Remote Desktop, see the related OS documentation and helps.

Telnet Server
In Windows Server 2003 for most Telnet Server functions, you do not need to configure Telnet Server
options to connect a Telnet client to the Windows Server 2003-based Telnet Server. However, in
Windows Server 2003 you must configure Telnet Server options to be able to do certain functions.
For example, the following command uses the credentials of the user who is currently logged on to the
client to create a Telnet connection on port 23 with a host named server01.
telnet server01
The following example creates the same Telnet connection and enables client-side logging to a log file
named c:\telnet_logfile.
telnet -f c:\telnet_logfile server01
The connection with the host remains active until you exit the Telnet session (by using the
Exit
command), or you use the Telnet Server administration tool to terminate the Telnet session on the host.
