samba stopped working after FC4 upgrade

[Avram Aumick]

I did an upgrade from FC3 to FC4. After the upgrade my client computer 
stopped
being able to access the server files or login to via samba. The message 
logs are as follows:

from log.client

I suspect that it has something to do with selinux. Howver I am not sure

Thanks for your help.
