Hi there,

I have a quick question that i hope you can help me with.

What is best practice for a Hyper V host running a virtual domain controller.

My client will be using One physical server running Hyper V 2012, this server will host a Virtual SBS 2011 server.

We are having a debate in work as to weather or not we should add the Hyper V server to the domain?

I have seen the below documents that stipulate the server should be added to the domain, but only if its part of a cluster.

Thanks

According to me and when I have reached so far best practice is generally not to have hosts machines on a domain. it is an additional infrastructure dependency that can put your environment at risk. It can be mitigated, but is an SMB the ability to mitigate is often low and the risks are higher. There is little gain by adding them to a domain so the gains seldom outweigh the risk

IMO it's better to keep the host machine as workgroup. However joining to the domain or not will not make much difference. When you install Hyper-V role, host OS also becomes a kind of Virtual machine!! so does not really matter if it's joined to the domain or not.

The recommendation for a cluster is to avoid a chicken egg scenario. If there is another dc then by all means, join the domain. But if your only dc is virtualize, you hit an issue where the host cones up and will want to authenticate against a dc is is hosting. And that can fail, making serviceability nearly impossible. So the decision isn't cut and dry. It is all dependent on the availability of your AD infrastructure.
