On one of our OES2 SP2 hosts we enabled CIFS to allow one client.
All the other clients have the Novell Client installed.

After about two weeks the root partition of the server was running
out of space. It was filled by /var/log/cifs.log.
Looking into cifs.log we found it full of messages about
workstations that are running the Novell Client.
I expected it should never talk to the CIFS server.

Here a short excerpt from the log.

The selected users (among many others) are all operating WinXP workstations
with Novell Client 4.91 SP5.

We have already verified the client settings of the UNC path filter and the
provider order.
This seems to be a OES2 Linux problem and not a client because we have never
seen this on NetWare.

Any suggestions?

Thank you in anticipation

Werner
