(redhat-6.1) gdm and exceed - connect with dynamic ip addresses

["avishay aton" <avishayaton hotmail com>]

I can login to the linux-server(gdm) only if i put
the IP address of the pc(which is assigned dynamicly)
in /etc/hosts.this is not a good solution,becuase
sometimes the pc get another IP addresses.
if i remove the entry from /etc/hosts, i can see only the
mouse cursor(X) and the whole screen without the login-browser!!
in th other hand,with solaris(cde) i don`t have this kind of problem!!
what is the solutions ?

Thanks to ALL(-:
