Gnome panel disappears with mounted NFS

[Guest zuomin]

I use Mandriva as the distribution as my servers.

The NIS account server and NFS file server (as home directory) is installed in a IBM server (named ServerA).

Several PCs (named ClientA )access the accounts and home directories from ServerA.

After setting, I can use ssh to remote login to ClientA, and every thing is work.

However, when I login to ClientA locally, I found that the Gnome panel on the top and bottom of the desktop are disappeared.

 

Later I found that when I login to ClientA locally as some account and the account's home directory are in the NFS file server, the Gnome panel will disappear. On the opposite, when the home directory are in the local file system, the Gnome panel works normally.

 

Does somebody meet this problem before? Or, is there some log file about the gnome panel?

 

Thank you very much.
