samba - Aug 2009 - BDC Promotion and Netbios...

We are replacing a failing PDC.  When promoting a BDC to replace an  
existing PDC, can you change the NETBIOS name field to match that of  
the original PDC without causing problems?

Sure, but you must reset the domain SID after you change the server name.

Before changing the server name:
	net getdomainsid

Stop winbind, smbd, nmbd.

Change the server name.

After changing the server name, and BEFORE starting nmbd, smbd, and winbind:
	net setdomainsid S-1-5-21-xxxxxxxxxx-xxxxxxx-xxxxxxxx
per the domain SID reported by 'net getdomainsid'

i'd probably just use netbios aliases = PDCNAME and rehash the config 
and see if that works first.
