Our domain is a child domain in a forest, and we only look after our own domain. Another organisation looks after the other domains. They have been very reluctant to make any forest wide changes for us in the past (e.g. schema extensions etc.)
The current domain (and forest) functional level is 2003. I want to raise our domain functional level to 2008 R2 (all our DCs are 2008 R2). I know I can do this independently of the forest. My question is this:
If I raise our domain functional level, does it actually change anything? Or does it just permit the forest functional level to be changed, once all the other domains are raised? (And only once the forest functional level is raised do the new features become available).
I know that the Active Directory Recycle Bin requires the whole forest to be raised (as it is dependant on a schema change). Does this apply to all new 2008/2008 R2 features?
