From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)


On two systems I have, when ever the nameserver specified in Network 
Configuration is down or unavailable for whatever reason (such as flaky 
network), it is near impossible to login as a normal user.  It just 
accepts the id/password, tries to start Gnome, but then kicks you back to 
the login screen.  On next reboot, you get the error message "According to 
gdm.pid in /var/run, gdm was already running (#) but was mysteriously 
murdered."  The screen will flicker and this message will repeat until you 
reboot.  When rebooting, 'Stopping X Font System' fails.

Reproducible: Always
Steps to Reproduce:
1. Add a nameserver
2. Try to make the nameserver unavailable for whatever reason 
(disconnected network cable, nameserver off, etc.)
3. Try to login several times
4. Reboot
	
Expected Results:  Should have been able to access desktop, graphical 
login screen should have come up again after reboot.

I forgot to mention that these problems linger even after the nameserver comes back up.

X simply does not work reasonably when you can't "ping `hostname`" - if you
can't resolve your hostname, the system is going to be screwed. 

Newer gdm in rawhide will just get stuck in a DNS query instead of getting into
this hosed state though. 

Still, even if you could log in GNOME and X wouldn't work right.
