Are you running a Windows firewall? I can't offhand remember which ports XDM and 
X require in order to work correctly. Certainly 6000 in order to contact display 
:0 on the PC, or 6001 for :1 etc. I have a nagging recollection that there is 
another port involved with XDMCP but I can't remember which. What traffic is 
XDMCP sending back to the PC? IIRC it needs to initiate a new connection on a 
specific port.

Setting up freenx/nx and the NX client is much simpler, and will provide you 
with a much better environment. We have pretty much abandoned Exceed in favour 
of NX.
