We've been running happlily on SBS 2003 for over 5 years now, and have another database server in the domain running Windows Server 2003.
We want to now add some redundancy to our network.
So we are interested in purchasing a new server as our primary domain controller, and creating a new domain.
We would link our database server to this domain, and use it as a backup domain controller, and as well would re-purpose our current SBS server as an additional application server.
I am seriously considering using Google Apps for our email now, to get that function out of Exchange.
Could someone please advise what kind of server I should consider for the main new server - should it be Server 2008, and if so would that allow a 2k3 server to be the backup domain controller?
I'd also like to see if it's possible to have the ability to run some virtual machines on the new server, or if that would be going too far.
