Why is there a Server 2008 32bit?
I've been setting up a 2008 Server to play with, and I chose to use the 32bit version mainly because It may become a print server in the near future and I don't feel like finding 64bit drivers for all the printers.
I decided to play around with the DC roles and to test drive Exchange Server 2007 on it.
ISA Server 2006 will not work on Server 2008 and apparently, ISA 2006's replacement, is only going to work on Server 2008 64bit.
Exchange Server 2007 will not install either, I'm in the process of downloading Exchange Server 2007 with SP1 (5.6GB!) but I see that is also only available in 64bit.
and lastly, Hyper-V will only be available on Server 2008 64bit editions.
So... why have they even bothered with 32bit versions if you're not going to be able to run any actual server software on it?
