I am removing the final Windows 2003 server after having migrated all Active Directory roles (FSMO) to 2 other Windows 2008/Windows 2012 servers.
When I run dcpromo on the Windows 2003 server, I am receiving the following prompt message:
Active Directory Installation Wizard
Before you can install or remove Active Directory, you must remove Certificate Services. For information about the consequence of removing Certificate Services, see Help And Support.
I had previously shut down the Windows 2003 server to check if any issues floated up, but there were none.
Any suggestions would be welcome.
