Hello! I have Lotus Notes 5.0.3 and the respective Notes client on a winframe server and several ICA clients as workstations. I don't know very much about Lotus Notes, other guys are managing it, all I can see is that the client is configured to create some files in the user's home directory called CACHE.DSK, DESKTOP.DSK and maybe some more. The home directories are on a Samba 2.0.5a server. Everything works without problems there except this Notes client. The symptom is: Every time a user is logged in to Notes client but doesn't touch it for about 20 minutes. When she tries to use it again after this break, it freezes immediately with an "unexpected network error" message. This happens always, perfectly reproducable. If I move the home directories to a "real" NT server, Notes client doesn't show this behaviour. What I tried is to tell Samba to refuse Oplocks for these files (*.DSK), then I switched off Oplocks for the whole home share. I fiddled with socket options and double checked the overall configuration but I had no success at all. Desperately looking for a hint where to search next! Tobias Galitzien, Channel One GmbH
