unfortuatly windows is not really a "remotely usable" os... there is not a whole lot you can do with a windows box from telnet... most applications are GUI bases, so when you run them from a telnet session, a gui pops up on the machines monitor... this is not very helpful...
there are a bunch of 3 party utilities that have been ported from unix to windows (sendmail, elm etc...) that you could install to add functionality from the command line....
You are probably better off installing PC Anywhere or VNC and "remote GUI" into the box instead...
