* Fast publish post – be nice..
In my Cloud OS demonstration environment recently I had a host in the cluster reporting “Needs Attention” status and refreshing the host cluster failed with “error 2912”.
The Hyper-V Host was in “Needs Attention” status and performing any functions from VMM were failing.
Job summary example below:
Error (2912)
An internal error has occurred trying to contact the server.domain.net server: : .WinRM: URL: [http://server.domain.net:5985], Verb: [ENUMERATE], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/Win32_PerfFormattedData_Tcpip_NetworkInterface], Filter: []
Unknown error (0xc0000bbf)
The basic tests (WinRM, DNS, Ping, Firewall etc) were indicating ‘communication’ was perfectly fine between host and VMM.
Found a post here that has several suggested resolutions and rebuilding the performance counters worked a treat for me.
From a administrator command prompt on the host:
lodctr /R
e.g.
By the time I switched back over to my VMM Console, the host status was “OK” so I refreshed the Host and all functionality resumed…
Not sure why this happened but the fix was fairly simple.
Cheers’
