- Sorry to jump on you Fred but the original poster is having problems with
- locking of the data files not the program files. I had a problem with
- Excel locking the data file and then not releasing the lock. As long as
- you were on the same machine (and same login) you could reopen the
- spreadsheet data file. If you went to another machine or logged in with
- another account then Excel would report the file was locked. The lock
- would be removed (of course) when the NFS server was rebooted and then the
- file could be opened once (and only once) on any machine.

- We have two machines providing NFS service to our PCs (24 hr student lab).
- One provides DOS program service only. It is exported read-only. It also
- provides authentication (via bwnfsd) and print service. The other server
- is the users' file server. It handles all the user space. This machine is
- shared with all the DOS, UNIX and Mac boxes in the CEC (Center for
- Engineering Computing) labs. Originally I did not run bwnfsd on this
- machine thinking it was not needed however because of the problem with
- lockd (the above problem) I started running bwnfsd to provide locking
- services.
