No errors found so it was not neccessery.

I added it to globals in smb.conf but could you explain why is it 
required and what it does?

I upgraded through ssh remotely from home, after talking on phnoe with 
one user at work it seems to work (login and GPO computer config). 
Toomorow will know if roaming profiles and logon scripts works ok.

Hope that DNS will work now without problem (dynamic updates) and will 
not have to restart samba every night becouse internal DNS gets stuck 
after few days of heavy load.
