XWin/xdmcp fails after PC domain change

[Greg Dotts <listmember at dottsfamily dot com>]

I could sure use some help solving a problem with my Cygwin/X (on MS XP 
Pro SP1 -> Fedora 2 xdmcp connection.

I recently changed my Samba server setup to PDC and joined my desktop 
and laptop PC's to the domain which promptly killed my Cygwin/X 
installations.  Step two was a remove/reinstall of Cygwin/X to the 
latest release on both machines.  This resulted in my laptop working, 
but not my desktop.  Next step was to remove the desktop and laptop from 
the domain and back into the original workgroup and try again.  I had to 
remove/reinstall Cygwin/X again, and again only the laptop will connect.

So now I'm scratching my head...  I have removed Cygwin/X from my 
desktop, cleaned the registry, removed all files related to Cygwin/X 
from the HD and reinstalled.  Same result - The XWin window loads but no 
response from the Fedora server.  Below is a copy of the XWin.log file 
and user variables, but I don't see anything out of the ordinary and I 
can't find any related entries in any of the Fedora logs.

BTW, nothing has changed on the xdmcp server side that I'm aware of... 
It looks to me like XWin.exe is not making the request to 192.168.1.1???

Any help would be appreciated and I've RTFM'd and searched the archives. ;-)
