Well my understanding is (and someone will certainly correct me) if you do a reversion from a snap shot that is too old then you have issues with objects that are deleted/changed . I imagine this could kick off a replication battle between DC's trying to decide who's copy of AD is correct.

DCs can be in Hyper-V cluster. Need to make sure that all virtual DCs cannot be on the same physical machine at the same time, which you will do by having them on separate clusters. The biggest gotcha, do not allow virtual DCs to get time from physical hosts. DCs must be able to get their own time. If Hyper-V hosts are domain members, then there should be a separate physical DC, so that Hyper-V hosts can authenticate when they are all booting. From: Robert Peterson [mailto:[email protected]] Sent: Friday, June 17, 2011 10:18 AM To: Active Directory Admin Issues Subject: Replacing DCs with new Hyper-V "guest" DCs? We have a good and maturing Hyper-V environment, multiple hosts with High Availability (Failover Clusters available) Our current DCs... hard W2003 Servers, are ready to be replaced. Tried to do some Googling... but it looked a little sparse of information or folks who have already moved to "virtual" DCs. Does anyone have some good links they'd share or experiences? I have (2) "clusters" of 2-Hyper-V hosts... 4 hosts in all. I am thinking a DC on each host, but NOT in the "fail-over" cluster, just one individual guest "DC" on each Hyper-V host. I would build the DCs as new 2008 servers. Sure there is a lot more I need to be thinking about, appreciate any feedback.
