We usually always keep 1 DC physical but have had the rest virtualized for a while without any major issues. Your sites are well connected T3, so how many sites do you have defined in AD (One per network and then the 2 DC's assigned to that site?)

Happy to hear ideas and receive links to further reading. Thx, Robert Current environment... Two sites with a T3 connecting both. Current DCs: (Qty- 4) "Hard server" Server 2003, two at each site. 20 various system servers each site. 700 users each site. Each site, has (2) Hyper-V hosts with High Availability within the site. Questions: Should I replace all 4 - "hard" DCs, with VMs? I was thinking a DC on each Hyper-V host, but not in the Fail-Over cluster...? Do I need 4 DCs, 2 on each site? Should I build at least one "hard" DC at each site? Been thinking Server 2008R2, should I jump to Server 2012 for the new DCs? Again, would love to hear everyone's ideas, and/or be pointed at some good reading.
