Upgrading from 2000 Functional Domain level to 2003 Functional domain level
Posted on 2014-07-29
I have a test setup in a VM environment of all our Production Domain Controllers in order to test the upgrade from Functional Forest/Domain level 2000 to 2003. We need to upgrade the level as we will be putting in a new Exchange 2013 server and this is a requirement
There are 3 VMs. We have (2) Server 2008 R2 SP1 Domain Controllers, and (1) Server 2003 R2 SP2 domain controller. In the virtual environment they all replicate to each other fine, I can open all AD service and everything works.
As soon as I go to the First 2008 Server ( Which holds all FSMO roles, and is a Schema Master etc...The big cheese) and raise the Forest Functional level to 2003, the system states the upgrade is complete and will tell the other DC's. I then try to open ANY AD service on the same box I get and error.....
"naming information cannot be located because the target principal name is incorrect"
This is driving me nuts as I cannot figure out why this is happening. This should be very simple to do
