I have a report from a customer that Mac users connecting to CIFS shares on OES2SP2 fully patched are seeing the following behaviour:

1) User mounts the shared folder at, for example, /share_folder

2) User opens some sub folder under /share_folder. The current directory is, for example, /shared_folder/sub_folder1/sub_folder2

3) A few minutes later, the connection will be refreshed and the current directory will become /share_folder automatically.

I am posting here first in case anyone has seen this; I know at least some are using Mac clients with CIFS e.g. the recent thread "cifs and macosx" of about 1 month ago. I might also open an SR on it.
