Lotus Notes, Oplocks, and Unexpected Network Error

[reinout.wijnveen at philips.com]

Hi,

Notes seems to be 'allergic' for any kind of reconnection to a network share if it has any data files on that share. I don't believe it's just *.nsf files. With older versions such a reconnection happened after an oplock break failure, newer samba 
releases copy the behaviour of NT: ignore and continue.

If you are on NT Terminal Server Edition please make sure that every user has it's own daemon (no users sharing a single daemon). That might be the reason that restarting the Notes Client does not help. In our case we also aplied the following to get rid 
of the remaing  "Unexepected network errors":

More information: technet Q233082

regedt32 
open:
HKEY_LOCAL_MACHINE\\SYSTEM\CurrentControlSet\Services\Rdr\Parameters

add value:

Value Name :		MultipleUsersOnConnection
Data Type :		REG_DWORD
Value :			0

We use Lotus notes with email files in mapped home directories on the samba
server. (RH6.2, 2.0.7).  I had seen some information on the list about NT
TSE with the same problem associated to oplock break failures.  I noticed
that if I restart the samba server, every single notes client would have
this "Unexpected Network Error" problem and you have to logoff and log back
on.  Killing and restarting the client didn't fix it.  I don't do that
anymore :)  Now its more sporadic, but still irritating.

Has anyone else seen this with Lotus Notes clients?

Even if you haven't, Notes stores it's data in *.nsf files, would something
like "veto oplock files = /*.nsf" accomplish the same thing as "oplocks =
False" without the performance hit for everything else on the server?


Thanks
