Andrew Bartlett told you what to do, if I were you I would follow his 
advice. upgrade your your machine to be a BDC and join it to the other 
If you are unsure just who Andrew Bartlett is, I suggest you google his 
name with the word 'samba'

What I think is happening: Samba is flat out refusing to change the 
local SID to the SID of the other machine simply because then there 
would be two workgroups with the same SID, how would it then be able to 
tell which machine was which?
