Samba Upgrade to 3.6.6 breaks it

view story

http://serverfault.com – I had a working system under Samba 3.5.6 (Debian Squeeze). I upgraded to Wheezy and Samba 3.6.6. Now no access to samba shares. Using windows server for DC. When I do smbclient -L server, I notice a difference. When it was working, the domain controller would be listed and Workgroup Master would show server name and domain controller. After upgrade, these are missing. Any ideas? Does this mean it didn't join correctly? (HowTos)
