The default setting for windows telnet server is NTLM authentication only. In order to use NC you have to change it to use plain text. Being as we’re talking command line here, enter tlntadmn, choose ‘3) Display / change registry settings’ then ‘7) NTLM’ and give it the value 0 (zero). This is not real secure to say the least but inside your home network for fun…what the hell. Don’t forget to include ‘-t’ in the NC args.

Oh yeah! Windows telnet does not allow a telnet session to be started from within the telnet shell but will allow a NC session. And if you plan to do a lot of command line work edlin is a good tool to learn as it works just great from within a shell and allows you to make changes to a single line without having to echo the whole dammed file.

As zark0id has said nc isn’t a GUI tool…it just sits there listening for incoming connections. The –v flag is pretty useless in a server use so try getting rid of it.
