We stood up a Domain Controller on a virtual (hyper-V) Windows Server 2008 R2 Enterprise edition Server for the purpose of installing Exchange 2010. We installed Exchange and doing so made some mistakes. We had to uninstall exchange from it. I created a new VM to put exchange on correctly. Now that Exchange is removed from that old DC, I want to remove AD from it and shut it down permanently. The problem is that it won't go down without a fight.
The old server I want to demote is "Exchange1.mydomain.net" and it is also a DNS Server
The primary DC is "server1.mydomain.net" and it is also a DNS Server
This is the error I get when I try to remove AD:
When attempting to remove AD using DCPROMO I get this error: "The operation failed because: the attempt at remote directory server server1.mydomain.net to remove directory server CN=Exchange1,CN=Servers,CN=mydomain,CN=Sites,CN=Configuration...
was unsuccessful. "Access is denied"
I have tried several different Domain Admin accounts and made sure that they were also
Enterprise Admins. Exchange1 can ping the primary domain controller. It is also a global catalog. To prove there wasn't some problem with the domain in general, I stood up another Test DC as global catalog and demoted it without any problems (without making it a DNS server).
What do the experts think I should do next?
Thanks in advance!
