Hyper V OS: Windows 2008 Datacenter
VM in question: Server 2008 R2 SP1
So, I'm having an issue wherein my NIC card on my Virtual Machine is momentarily disconnected, interrupting an important service that must be manually restarted. This happens quite intermittently, weekly or bimonthly, but it is annoying and disruptive. Netsvc is the service, and the message is that the card disconnected, then another netsvc event for the reconnect.
I turned the powercfg.cpl settings on both HyperV host and VM to High Performance mode (a solution I found online) and still have the issue.
The thread "Microsoft Virtual Machine Bus Network Adapter keeps disconnecting" (link withheld due to the settings on this forum) appears to partially describe the issue, but the hotfixes listed by Mr. AlessandroCardoso are not compatible with my Hyper V or VM, so neither are valid (obviously not the 2003 one) in my case.
The hyper V integration tools are installed.
