I am a linux person by trade, so this windows stuff confuses me.
I am going to setup a PDC and BDC, and I need another windows server license for a storage server.
I have a MAPS license which includes WinSrvr Standard 2008 (not R2), Enterprise R2. I have been quoted for a WinSrvr2008R2 OEM license with the new BDC.
Can I use, for example, Server 2008 R2 standard as the PDC, and Enterprise R2 as a BDC or vice versa, or do they have to be the same edition of windows?
The Storage Server can be 2008 Std (non-R2)
To answer your questions yes you can do what you propose. I would however if possible swap to enterprise for your PDC but at the end of the day it shouldnt matter to much for you.
