Windows Server 2003 has the Telnet disabled by default (and so good that it does!)
To have the Telnet service running on Windows Server 2003 follow the next steps:
- Go to the Services applet in Administrative Tools (or click Start, then Run, and type "services.msc" (without quotes) and click OK).
- Find the "Telnet" service, right-click and select Properties, select "Automatic" instead of "Disabled" in the startup type box.
- Click Apply.
- Right-click the "Telnet" service and select Start.
- Click OK.
You can also modify start state and start it from a Command Prompt console by using the following command:
sc config TlntSvr start= auto and sc start TlntSvr or net start TlntSvr
Configuration for Pre-W2K/XP/2003 Clients:
The Telnet server requires NTLM authentication by default. To deactivate this and use only password authentication, use the tlntadmn command:
tlntadmn config sec=-NTLM
Also, switching to streams mode may make display easier for Unix/Linux clients. Do this with the following command:
tlntadmn config mode=stream
