I get this error message whenever I start up

Could not look up internet address for x1-6-00-04-5a-63-10-c9.
This will prevent GNOME from operating correctly.
It may be possible to correct the problem by adding
x1-6-00-04-5a-63-10-c9 to the file /etc/hosts.

It dosn't happen with KDE. I added the specified data to the file, but when that was there it took forever for linux to start??? weird? And when I removed it it started up normaly, and I'm not talking about when you log into the specified user. It does it on the boot. I don't know if this is a problem many people have had or have, but I re-instaled my os and it still percists, could someone please help me?

Zeth,

Add this into your /etc/hosts if its not already there or not.

127.0.0.1 localhost

Thank you but this did not work.

Well your on DHCP I presume so it somewhat needs your hostname in your /etc/hosts file in which that. What is the name of your machine, hostname ? Type hostname to find name of your machine. And can you give us the output of your /etc/hosts file here ?
