Hope you're fine.
I just wanted to know if there's a difference between :
-An Active Directory Domain controller with the Windows server 2003 domain functional level
-And using the whole Windows Server 2003 operating System ?
The purpose is that I'm not familiar with WinServer2003 and I wanna use WinServer2008R2, but I've been told that the ADDC should be running WinServer2003.
So does it matters if I use the 2008R2 version of the OS to make it ?
