I am using PC-NFS to mount a remote drive on a Sun 386i.  This
particular file system is also mounted by several other PCs and hence
is mounted with the /MS (MustShare) option.  I have been getting
errors which until recently I haven't even been able to find the
reporter let alone the cause and I hope that some one else may be
able to throw some light on the DOS behaviour and consequently the
NFS behaviour.

Command.com's critical error handler reports the error,

Sharing Violation
Abort, Fail ?

Neither A nor F normally succeed in doing anything, the message is
simply repeated and the PC must be rebooted.

Today I finally managed to get this error to occur when simply doing
a DIR on a directory on the remote drive.  I did manage to get back
to a prompt and ran NET USE, it reported

D:  /MS?  etc etc.

I have never seen the ? after the MS before and assume PC-NFS is
considering the sharing to be suspect ?

Dismounting and Remounting the drive returns it to the normal /MS
status.

Can someone tell me what Sharing Violation means, from the DOS
perspective.  What is being violated ? In the case above no locking
was being done that I was aware of.

Has anyone else running PC-NFS ever seen this behaviour before and
found a remedy or at least an explanation.
