In regards to having DCs virtualized. We have 15 DCs and only 2 of them are physical (PDCe and another GC). When we bring down the data center for a recovery exercise or a scheduled power outage, we need to have AD come up first since other things are authenticating against it. This makes it much quicker then waiting for the VMWare environment to come online. Another benefit is that if there is an issue with the back end storage where the VMWare LUNS reside, we have something to authenticate against until it comes back.
YMMV ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
