[Samba] Messed up SIDs: How to change machine SID?

[Marcus Mundt]

Dear Samba Gurus,

I got the following errors:
tail -f /var/log/samba/log.wb-DOM1

I guess the reason might be this:
net getdomainsid
SID for local machine M1 is: 	S-1-5-21-3981825222-1828954701-2606613544
SID for domain DOM1 is: 	S-1-5-21-2762780445-1763757571-3541238449

net getdomainsid
SID for local machine M2 is: 	S-1-5-21-2913448378-2543514743-1508345481
SID for domain DOM1 is: 	S-1-5-21-2762780445-1763757571-3541238449


Shouldn't the SIDs be the same except the last digits???

Cheers,
Marcus
