Raising the functional level of the domain from 2000 to 2003
Has anyone had any experience of raising the functional level of the domain?
I plan to raise the functional level of our domain from 2000 native to 2003. I have done some research and it appears as it only affects the way DCs communicate with each other (and the internal ADS database of the DCs) and not how member servers/clients communicate with the DCs, so it should not cause many or any issues.
All the DCs are 2008, but I thought that a smaller step (to 2003) might be preferable.
As a precurser, I've checked the event logs on the DCs for any errors, ran a tool to verify replication, deleted a lot of old GPOs and old network accounts, and done a full backup of a DC (to get a snapshot of ADS)
The main reason for raising that another project that I am working on (Data Protection Manager 2010) requires the level to be 2003 (or more).
We have OFSTED coming in a couple of weeks, so I think we will gave to defer raising the level until after the inspection, just in case.:rolleyes:
