Could not look up internet address for

["Gregory P. Ennis" <PoMec PoMec Net>]

Everyone,

I have been tweaking a new Linux Fc4 installation and changed the name
of the machine from old.domain.net to new.domain.net by changing the
name in Network Configuration module by going into the tab labeled DNS
and changing the hostname from old to new.  

After I did this I keep getting the following message when I login using
gnome.

"Could not look up internet address for new.domain.net.  This will
prevent gnome from operating correctly.  It may be possible to correct
the problem by adding new.domain.net to the file /etc/hosts."

I have tried doing what the warning suggested, but there were no changes
in the warning.  

This may be an easy fix but I can not find a reference to point me in
the right direction.  

When the name is changed on a machine is there more than one place to
change the name. Any help would be appreciated.

Thanks,

Greg Ennis
