I have changed the mounts to to tcp and added the no_subtree_check to the 
server. I have also disabled IPV6 on the desktops anyway... so far no 
complaints. I am wondering if the last "its slow" complaint was justified!! 
The system seems to work fine and then one of the desktops will just grind to 
a halt. For example - usually to open OpenOffice takes a few seonds, this can 
increase to 45 seconds when the system "plays up" and KDE can take 5-10 
seconds to open a menu. Checking top I don't see much activity so its not an 
issue with desktop cpu or memory resources. Most frustrating of all its 
intermittent. A reboot clears the problem. It might not raise its head for 
hours or even days.

The server is Mandrake 9.1 (nfs v2)

The desktops are Mandrake 10.2

I will see if I get any complaints tomorrow.
