[Samba] PDC appears to be BDC in server manager

[Martin Brook]

Thanks for replying. My smb.conf is below.

But I did get a bit further with this last night - I think the problem
may have been caused by me changing the netbios name of the server.

It was originally called BIGSERVER. The server I used as a temporary
BDC was called LITTLESERVER. When I copied everything back over to
BIGSERVER, I changed the 'netbios name' in the smb.conf from
LITTLESERVER to BIGSERVER.

Suspecting that this might have been connected to the problem, I
changed it back. This made no difference until I found a suggestion to
delete wins.dat and browse.dat. Once I'd done this (with samba
stopped), I found that user manager and server manager are now loading
up without errors, and LITTLESERVER appears correctly as "Windows NT
Primary".

But I still have some problems:

1. I'm still getting 'access denied' when I try to add/remove machines
in Server Manager, or modify user accounts in User Manager.

2. I somehow need to rename the server back to BIGSERVER, but I'm not
sure how to do this without breaking things again.

Thanks for any help anyone is able to give! I'm crossing my fingers
that I can get this fixed today... users will be back tomorrow!

Here's my smb.conf with all of the comments taken out..
