recently, I had some occurrences of the following error while scanning the compliance state of particular hosts or clusters from SCVMM:
A Hardware Management error has occurred trying to contact server <hostname> .
WinRM: URL: [http://<hostname>:5985], Verb: [INVOKE], Method: [ScanForUpdates], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/scvmm/UpdateManagement]
Unknown error (0x80338043)
WinRM is installed and running on server <hostname>. For more Information use the command "winrm helpmsg hresult" and http://support.microsoft.com/kb/2742275
This happens because the answer of the host with the installed Hotfixes grows larger and needs to be fragmented. Here WinRM Needs to be updatedt to a later version.
To solve this problem you need to install “Windows Management Framework (WMF) 5.0” at least on your SCVMM Server.
At the time of this writing the Production Preview of WMF 5.0 is available at https://www.microsoft.com/en-us/download/details.aspx?id=48729
