Kim,

Thanks for your reply. Lots of things there!  I have merged my answers with 
your questions below although haven't tried everything yet. Perhaps my 
answers might give a few more clues to the problem though.

>Is /afs available on other AFS clients?  That rules out some possibilities.

Yes, on some of them. 50% have this problem though.

>I'd go to a well-behaved client, cd /afs, fs flushv, cd /afs and see if 
>/afs
>is still available on that client.

Yes, tried this and /afs was still available.
