I had a situation that all Hyper-V hosts (Windows Server 2012R2) in a failover cluster are on “Need Attention State” in System Center Virtual Machine Manager 2012R2. A reboot of those servers or refresh the servers in SCVMM doesn’t put those servers back in an “OK” state.

In the job event log of SCVMM you can find the following warning:
A Hardware Management error has occurred trying to contact server servername.domain.com :n:CannotProcessFilter:HRESULT 0x8033801a:No instance found with five property values.

hardware-management-error

A Hardware Management error has occurred

The recommended action of Microsoft is to check whether WinRM is installed and running on that server… (See http://social.technet.microsoft.com/wiki/contents/articles/4902.system-center-2012-virtual-machine-manager-vmm-error-codes-2500-2999.aspx)

What I suggest to check is the following:

  1. Check whether the SCVMM agents on those hosts don’t require an update via the SCVMM server.
  2. When all agents are up-to-date, then the following you should do…
    The problem can occur if the shared svchost.exe process that hosts the Windows Remote Management (WinRM) service is experiencing issues.
    Use the following command in an elevated command prompt: sc config winrm type= own
  3. Increase the default values for the WinRM service with the following command in an elevated command prompt (when having Error 0x8033803b):
    Increase the time out value for the Agent to contact the VMM Server by using this command:
    winrm set winrm/config @{MaxTimeoutms = “1800000”}
    Increase the number of threads that can be sent to the VMM Server by using this command:
    winrm set winrm/config/Service @{MaxConcurrentOperationsPerUser=”400″}
    net stop winrm
    net start winrm
    net start scvmmagent

SCVMM depends on the Windows Remote Management service for host communication. Therefore, the “Not Responding” status is very likely to occur because of an error in the underlying Windows Remote Management communication between the VMM server and the host computer.
