Check the hosts file and make sure each machine has a reference to itself
that does not require DNS to resolve.

If the box has a single interface which uses DHCP, then you should assign
a real name to the loopback interface, in addition to localhost:

  127.0.0.1 localhost.localdomain localhost realhostname.realdomain realhostname

That way, when gdm tries to make a network connection to realhostname, it
will resolve to 127.0.0.1 instead of querying the DNS.
