Try doing this on the file server:
Disable opportunistic locking on the client and the server. Disable it on
the
server first, then reboot, test, if the error still occurs then disable the
oplocks
on the client, reboot and test it. Here's how to disable the opportunistic
locking.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
\Services\LanmanWorkstation\Parameters
UseOpportunisticLocking REG_DWORD 0(off)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
EnableOplocks REG_DWORD 0 (off)
Opportunisitic locking is enabled for performance only, so disabling it
might result in a very slight performance hit. That's the only effect of
disabling it.
