That was not my impression from reading information about XP SP2.

However, I don't think we are going to have to modify anything anyway, 
since the default for the new firewall in SP2 is to allowing incoming 
connections for a few seconds from the remote host after an outbound 
connection has been made to it.  This should work just fine with our 
outbound UDP connection that expects to get a return TCP connection for 
Xdmcp.
