The use of SHARE is completrely irrelevant, although if you start it
after PC-NFS it may confuse things (I'll try it in a few minutes).
The server must be running a version of the lock manager which supports
the PC extensions: run
	rpcinfo -u servername  100021 3
and if you see
	program 100021 version 3 ready and waiting
all is well. If you see
	rpcinfo: RPC: Program not registered
	program 100021 version 3 is not available
you should install a copy of the modified network lock manager
from the PC-NFS distribution kit. Then make sure that when you
mount the drive in NFSCONF you select
	Use lock manager (required)
for "Options"; if you prefer to run NET USE by hand, append a "/MS"
switch to the command.
