We have 2 Domains, both domains have 2 DC's
DC1.companyA.local, DC2.companyA.local
AND
DC1.companyB.local, DC2.companyB.local
DC1.companyA.local was imaged (but SID was NOT reset using sysprep properly before deployment -ARGH!!) and the image was restored to create DC1.companyB.local
Now, we can't create a Domain Trust because of the duplicate Domain SID's :(
What is the appropriate process to follow to get this working now?-- keeping in mind that we have 2 domain controllers on both domains.
If the process is Demote - Unjoin domain - sysprep... Then should I do this on the secondary controller first, and then on DC1? Or do I have to create a whole new domain from scratch to ensure that the Domain SID is properly renewed?
Also, will I have to rejoin All 150 of my workstations to the "new" domain?
Thank you in advance!
