Problem creating a new domain tree in an existing forest (win 2000)

Hi there,

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?

Thanks,

Mike

With AD Domains and Trusts it is looking for the role of Domain Naming Master when you select operations master...

Apparently, the role wasn't transferred when a new domain controller was built up in the past, thus I had to seize the domain naming master role on domainA.

For anyone that is having this same problem, here are a couple of links that helped me..

This next one, you want to click on operations master and scroll down to the table, just above that explains the Ramifications of a Role Seizure..
