What does this error mean?

I have RH8.0 Linux. When I log in (KDE) I get the following error:

"An error occurred while loading or saving configuration information
for rhn-applet. Some of your configuration settings nay not work
properly"
In the details it says: "Failed to contact configuration server, some
possible causes are that you need to enable TCP/IP networking for
ORBit, or you have stale NFS locks due to a system crash. (Details -
1: IOR file '/home/.../.gconfd/lock/Ior' not opened successfully, no
gconfd located: No such file or directory. 2: IOR file
'/home/.../.gconfd/lock/Ior' not opened successfully, no gconfd
located: No such file or directory."

Also I'm not able to login in Gnome. The screen is a mess.

I'm not sure I can understand what it's saying. Can someone suggest
what may be wrong and what to do to correct it?
Thanks

I think you are setting somthing relating with Redhat Network. THat web site is used for automatic maintain your OS platform. Try reconfigure it.

Actually no. I already found the solution. It was a damaged gconfd. I just deleted it, together with gconf and Linux created a new ones. Now everything is fine.
