My current setup is a Windows 2003 Server with Exchange 2007 that acts as the Primary Domain controller, I also have a second domain controller that is a Windows 2008 Server. A few days ago when I added the Windows 2008 server to the domain, i was required to do the "adprep" commands.
Everything looks good right now.
My question is, I want to install SP1 on my exchange server, but I have gotten mixed comments saying that I can not install SP1 on a 2008 server (witch I am not doing) but does the adprep make it imposable to install SP1 on the exchange server running on top of Windows 2003?
so, can I install SP1 on the 2003 server even after the domain was prepped for a 2008 AD updates?
I hope this is understandable.
