I had a PDC and it’s BDC. But the Exchange Server hosted in the PDC crashed and I’ve had to re-install the PDC. Of course (I didn’t realized), a new domain (with the same name!!!) was created. Now, what do I have to do to re-join my existnig BDC to the new domain (with the same name)? It’s mandatory cause both servers are complaining about SAM databases, ACL’s e etc. They are not synchronizing! Users have 2 passwords, one for each server! Thanx and sorry for my english.
