We have a single child domain (1 2003 R2 DC) that we can not touch (dont ask why!) and I need to upgrade our AD schema from 2003 R2 to 2008 R2. I am assuming that I start withthe Domain Schema Master and Infrastructure Master servers in the root domain before I touch the child domain? Also I have been told I may not be allowed to change the child domain at all so what kind of issues will this cause?
Thanks.
Thanks.
