Alright, I have an odd problem I am facing. First I have a mixture of physical and virtual servers, the virtual hosts run Hyper V. All of the OS's are Server 2008 R2. We have an issue where, after say, a power failure, the Hyper V host runs poorly. There are two server 2008 r2 servers on the network, both are DNS servers, and if you power down all of the servers and just let the Hypver-V host boot first, there seems to be no issue. If the domain controller that is physical boots up before the Hyper-V guest does, then all hell breaks loose and the Hyper V host runs so slow that it is barely usable. We have set the DNS server settings on the NIC to point to the physical DNS server first, then to the DC that the Hyper-V server is hosting second thinking that the host was having issues finding resources on the network, this did not seem to solve the issue. So in short, when the Hyper V host is booted all by itself first, no issues, if the physical DC comes up first, hell breaks loose. I checked the event viewer and did not find any DNS related events, so I am a bit stumped. I know this is kind of a complicated issue so if you have further questions please let me know, thanks!
