I am wondering how best to remove and Orphaned AD Domain Controller. A customer has an SBS2008 server running as a Domain Controller. They had an original Server 2008, also acting as a Domain Controller, but they pulled the server off line some months ago and got rid of it.
My problem is that the SBS2008 server will not allow me to install Exchange SP3 because it needs to synchronize with the other DC before proceeding.
There are other problems that I am attributing to the Orphaned DC. What is the best approach to removing this DC and clean up Active Directory.
I am reading articles that give you detailed instructions on removing in a mixed environment (2000/2003/2008) and then I read other articles that say it is easier in 2008. I am confused.
