Telnet to 515 Problems

I am trying to setup a UNIX computer to print into one of our remotely
Windows 2003 servers. I have installed the Print UNIX services at the
server. I add a new LPR printer at the server. For some reason, I am not
able to print to the new printer. When I try to telnet to LPR (Port 515) I
get the following message:

"Connection to host lost."

I am not getting the regular blank screen.

I would like to know why is this happening? Is this normal under a Windows
2003 server? When I tried the telnet to 3389 it works fine.

Please advise if you have any suggestions.

Thank you!
