Adding Server 2003 R2 into exisiting Server 2003 domain.
Posted on 2007-03-22
Before I go mental can someone please help with this problem.
We have an existing server 2003 domain, the PDC is running server 2003 SP1.
I have just installed a new server running Server 2003 R2, however it will not allow me to add it as a DC. It informs me that I need to run ADPREP on the PDC. This is in contradiction from this taken from the Microsoft Support site:
"When you change the schema on the schema operations master, the changes are automatically propagated to all other domain controllers in the forest. Therefore, it is not necessary to perform this operation on other domain controllers. Also, there is no need to run Adprep /domainprep when installing a domain controller running Windows Server 2003 R2 into a domain where there is an existing Windows Server 2003 domain controller running Service Pack 1 (SP1); this is because the necessary domain partition updates were done when Windows Server 2003 SP1 was installed."
We do not have the luxury of a lab to test the ADPREP into our domain so we only get one shot.
What are the risks other than breaking the PDC?
