You don't have the same home directory on both machines? In that case,
the .Xauthority file is shared and the clients on the remote machine
know the magic cookie for the display. (all this assuming that you use
either xdm or another way to start your X-server with the -auth
option). 

Otherwise, could there be something in your sequence of startup files
which changes the access list of the server?
