The functional level of the domain or forest is incompatible with this operating system
-
Trying to promote Server 2008 when the domain and forest functional level is at Windows Server 2012R2. I get:
The functional level of the domain or forest is incompatible with this operating system."
Do I have to lower the domain or forest level to get the 2008 server to promote? -

But, more importantly, why on earth are you trying to promote such an old OS as a DC? -

Okay, this one should be obivious the functional level is at 2012R2.. therefore nothing older than 2012R2 can be a DC.
Make a new server 2012r2 VM as a DC. Do not try to lower functional level, this a bad idea.

I agree - don't try to lower the Functional Level. If you don't have the funds to buy a 2012 R2 server to run as a DC, check into running Linux as a DC in a Windows forest. It will be free.

I don't believe that Samba4 can support anything later than 2008R2 functional level, though. If it does, it's very new.

@scottalanmiller yes samba only supports 2008r2 funtional level still.

Oh - that sucks! I wonder what the hold up is? That's a whole 2 versions behind, and almost a third.
