I assume you got version 3.4.3-3.2.1-2306-SUSE-SL11.2 from opensuse update which replaced version 3.4.2-188.8.131.52-2229-SUSE-SL11 from opensuse OSS. Several people in the forum including me had the same problems with Samba after the update. You need to downgrade all files back to 3.4.2-184.108.40.206-2229-SUSE-SL11 from opensuse OSS and all should be back to normal.
You could elevate the priority of opensuse-OSS in your repositories (giving a lower number) and then upgrade all files that show up on a samba search + cifs, that would work. For any file loaded in openSUSE, you can check the version tab and pick a different version up or down by file as an alternative. If you do not have the opensuse-OSS repository present, you need to add it back.
Thanks for the reply. Downgrading the package fixed the problem. Now I just have the annoyance of yast prompting me to reinstall the security update that caused the problem, but I guess I can live with that.
I have not reported the problem to anyone outside of talking about it here in the forum. I have duplicated the issue on two different computers with the solution still the same, down grading the Samba version. Oddly, the issue seems to kill the Samba Client from being able to browse the Workgroup even as Samba the Server still serves up your shared folders for everyone else to use.
According to bugzilla the problem is known and fixed and just waiting to be tested and packaged. Got no idea about a time line. If you must have the functionality you need to drop back to the previous version and lock the package(s) but then you won’t get notified when the ultimate fix comes along, and you will just have to check every once in a while manually.
