I have a Windows Server 2012 R2 Standard box that I was trying to set as a second domain controller, but ran into some problem and now it's stuck in promotion limbo.
I cannot promote it because I get the following error:
Error determining whether the target server is already a domain controller: The domain controller promotion completed, but the server is not advertising as a domain controller.
I am also unable to remove the AD DS role because DC needs to be demoted, which I also cannot do. When trying to demote it, I get the following error:
The operation failed because:
DFS Replication: The target principal name is incorrect.
"The target principal name is incorrect."
/netdom query fsmo
sometimes shows the correct information and other times returns
The target principal name is incorrect.
The command failed to complete successfully.
I'm not a Windows Server expert, so this has me stumped. Any advice would be greatly appreciate.
Thanks in advance.
