smbfs enabled but not working

All, YaST > System Services (Runlevel) shows that nmb and smb are installed and enabled, while smbfs is installed and enabled, but has the asterisk (*) indicating that it is not working. If I select it and click "Enable", an info/dialog pops up saying: /etc/init.d/smbfs start returned 6 (program is not configured): Mount SMB/ CIFS File System ..unused [OK] A populated smb.conf file exists, so I assume this must be looking for some other file, in order to feel "configured". Anybody know what needs configging, here? Is it accessible via a YaST dialog, or do I create/edit a file directly? Kevin
