Can't speak to Win2K, but for NT, a socket bound to 
'localhost' will not be visible outside the machine; the 
machine's network name should work fine from both 
machines, but you probably need to list it in your HOSTS file 
(which on NT is in the obvious <wink> location of 
system32/drivers/etc).

I doubt this has anything to do with the "RPC service", which 
is really an MS variation on DCE RPC.
