This article describes the differences between the Windows 2000 Telnet client and the Microsoft Windows NT version 4.0 Telnet client.
Telnet for Windows 2000 does not have a Graphical User Interface (GUI). You must start it from a command prompt.
If you are attempting to use Telnet to connect to a member server that is using basic security, you must have permissions to log on to the local computer. If the server is using challenge/response (NTLM) security, then you simply logon to the server from the network (as you do in a file share).
The Windows 2000 Telnet client supports challenge/response (NTLM) authentication. With NTLM authentication support, a Windows 2000-based Telnet client can log on to a Windows 2000-based Telnet server by using NTLM authentication.
NTLM authentication was introduced in the Services for UNIX (SFU) version of the Telnet client for Windows NT 4.0. The basic Telnet client for Windows NT does not support this feature.
Telnet session logging is not supported in the Windows 2000 Telnet client.
For more information about Telnet commands, type telnet at a command prompt, and then type help to see a list of commands.

226107NOTE: To use a GUI-based Telnet client on a Windows 2000-based computer, obtain a copy of the Telnet.exe file from a Windows NT 4.0-based computer, rename it to Telnet32.exe, and then copy it to the Windows 2000-based computer. Telnet.exe is located in the C:\Winnt\System32 folder.
