My first question is why are you looking to replace your domain controllers right now? What's the driver? Old hardware at EOL? Off lease? Moving to 2008 FFL/DFL? Single Forest ? Single domain? Going under the assumption that you have a business driver, I would suggest having one physical DC at each site, and one virtual at each 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.
