I have a current domain that is in production right now.(DomainA)
My company has a need to have a second domain (DomainB) that I will administer as well.
While going through the DCPROMO process for the new domain, I selected create a new domain, create a new domain tree in an existing forest, name the domain (DomainB.com) , supply credentials for DomainA etc....
When it gets to the point of creating the domain an error comes back stating that DomainB.com could not be determined as unique on DomainA..
So, I think, ok this is an operations master problem??? During some of the research I can verify the correct DC has all the FSMO roles on DOMAINA through AD users and computers, but not in AD Domains and Trusts?
I have read about the seize operations master comand, but I am not sure that is the answer as I can see that the correct DC using the AD users and computers snap in??
Any idea on what I can do to start solving this?
