X cannot open connection

[Per Otto Opstad]

I have used X for a while now and everything worked fine until now.
 
Suddenly i only get the "disconnected" screen all the time. This is the
same screen you get when you plug out your LAN cable.
I have tried to restart my computer - no change.
When i use cygwin i can ssh to the computer i try to connect to. I use
no firewall.
I try to run: C:\cygwin\usr\X11R6\bin\XWin.exe  -query 10.0.0.62
Do you have eny idea on what's causing this? I get no warnings when
starting up.
