Ok, the last post suggested that I try to run XDM in debug mode. In order to do that you must drop out of the display manager. In order to do that you must change to run level 3 since there is no such thing as an XDM stop command.
I did the following: telinit 3 xdm -debug 10 -nodaemon telinit 5 I assumed I wanted to get back into the default run level 5. After doing the above sequence of commands, it turns out that two displays get launched on my linux server. "0" which is the display that was dropped to run level 3, and "1" which is in run level 5. We get a msg that says hey display 0 is busy launching display 1. I don't think this was your guys intent. So I did the following: telinit 3 xdm -debug 10 -nodaemon & (so I can keep my ssh window) When we do this the guy on the Win2K box can no longer login, (no one else either). I hard reboot the linux box, and now the Win2K box can login.

I don't know if this makes a difference. From my WinXP box in question, I can ping the linux box, I can SSH to the linux box, I can do a nslookup on the IP for the linux box.

Rember, this is my first time working with Cygwin. After installing a full Cygwin install, is there some configuration for the Xserver (my WinXP Xclient in this case) that I must do? Something you experts have overlooked since its so obvious. In my WinXP C:\Cygwin\etc folder thare two files, "hosts.allow" and "hosts.deny". Am I supposed to have done something with them? Are there other examples of something that needs configuring on the "client" side?
