samba - Jun 2005 - currently no logon servers available to service logon request

Hi all,

My Samba server with winbind in an NT4 domain ran fine for a year, now this
message is all we get from the windows side.

Can it be because it is not listed in the WINS?

Whe I look at it from Svrmgr in NT then it says access denied.
The same happens using net view

Why does it not register with the WINS server?

If I configure Samba as a wins server - will it run together with an NT WINS
server?

Thanks for any ideas
