I have several sites that have a single physical Hyper-V (full) 2012 R2 Server. The Hyper-V host server is not in the domain. One of guests in an Active Directory Windows Server 2008 VM. The other couple of guests are Windows Server 2008 member servers that belong to the domain.
Integration Services is implemented for all the guests, including the active directory server.
I believe the active directory server is the authorative time server for the domain.
I suspect the domain server time sync is implemented but that the Integration Services time sync is also implemented and worry this could lead to odd time sync issues.
What's the best practice in regards to how this type of configuration should be setup? Integration Time Sync turned off on one or more of the VMs? Domain style time sync turned off somehow? Custom registry mods? Nothing?
