I have a Hyper-V VM (Host an VM are Windows 2012 R2) that work fine this morning and after 1 hour after employed begin to work, it began to have many problem, most are network specific. It is a DC. This week-end we had a power outage, so I think first that it come from there. I tried to find the problem but it that something is stuck somewhere. many service seem to initialising but stay there or many doesnt seem to start. But there nothing in event log. I have a remote access program on the vm and it is not start, Sql server don't respond, RDP don't respond and many other service don't respond but all share work fine. Internet access is working.
When I check windows activation it said product id unavailable. I tried to reinsert the key but it seem to work without stopping. The key come from an open licence account and it is use on the host and it work fine on it. When I check the maintenance manager it said maintenance running. I tried DISM.exe /Online /Cleanup-image /Scanhealth but it did nothing after 2 hours.
I have in server manager I have problem with managability, it said, online - data retrieval failures occured. I have an other problem reported by server manager for the automatic refresh: Configuration refresh failed with the following error: Call was cancelled by the message filter.
When I shut down the server it stuck on Stopping service :
I tried restore a 1 month old vm backup and start from there but it does the same thing. That's very weird. Is it something with the host? No installation or update was made on the host or on the vm.
I'm not a Windows server master, somebody can help me with this problem?
