We have 2 domain controllers, DC1 and DC2.
The Current Forest Functional Level is Windows 2000 and the Current Domain Functional Level is Windows 2000 Mixed
DC1 is Windows Server 2003 SP2, DC2 is Windows 2000 Server SP4
We are doing some planning to raise both the Forest and Domain functional levels. However, when we go to Active Directory Domain and Trusts and choose Raise Domain Functional Level, the only option available under 'Select and available domain functional level' is Windows 2000 Native.
My question - How come Windows Server 2003 is not available as an option under 'Select and available domain functional level'?
Must I demote the DC2 first before I can see the Windows Server 2003 as an option?
