From any machine with a telnet client, you can just open a command line and type telnet machine_name, where machine_name is either the DNS name or IP address of your server.Telnet is a command-line protocol that is used to connect remote systems over the network and manage them with commands.

Here's how to tell a server's telnet server software to accept standard telnet logins:ġ. You can do that, but again, be warned that allowing standard telnet clients to attach requires allowing clear-text passwords-check with your security group before doing this. On the other hand, you may decide that you'd like remote administrators to be able to log in with any kind of telnet client rather than just the Windows 2000 client. From there, you can do anything that you can do from the command line: run batch files, run scripts, or use command-line versions of utilities. (Other Windows operating systems will not be able to connect to the telnet server unless you edit the server's settings to allow it to accept passwords in clear text I'll explain how to do this in just a minute.)Īssuming that you're already logged onto the domain, you can just start a session from a command line by typing telnet servername, where servername is the name of the server that you want to establish the telnet session on. It requires not only a modified telnet server but a modified telnet client as well-but Windows 2000 comes with a client like that. Instead of using clear-text passwords, it uses an NT-style authentication approach called NTLM. While telnet is often a potential security risk because it passes passwords in clear text over the network, Microsoft has reduced that risk by modifying the way the telnet server behaves. You'll see a single-selection drop-down list box labeled Startup choose Automatic, then click OK to close the window.

Alternatively, you can tell your system to always have the telnet server available by setting up the telnet service to start automatically. You can start it by just opening up a command line and typing net start tlntsvr and pressing Enter. Telnet is built as a service under Windows 2000.
