I recently had to troubleshoot an issue on a System Center Virtual Machine Manager 2012 (SCVMM) SP1 server.
All the managed hosts were in a state of “Needs Attention”. When viewing the status screen for the host, the WinRM status was critical. Pressing refresh in the host status screen resulted in the error message:
VMM does not have appropriate permissions to access the resource on the %SCVMMSERVER% server.
Also, verify that CredSSP authentication is currently enabled on the service configuration of the target computer %HOSTSERVER%. To enable the CredSSP on the service configuration of the target computer, run the following command from an elevated command line: winrm set winrm/config/service/auth @{CredSSP=”true”}
The event log also contained the error:
The Virtual Machine Manager management server could not copy a required Hyper-V authorization file to %HOSTSERVER%.
After trying many things without success, I attempted a re-install of SCVMM. This also failed with the message:
VMM does not have appropriate permissions to access the resource on the %SCVMMSERVER% server.
The SetupWizard.log contained the message:
VMMPostinstallProcessor threw an exception: Threw Exception.Type: Microsoft.Carmine.WSManWrappers.WSManProviderException, Exception.Message: VMM does not have appropriate permissions to access the resource on the %SCVMMSERVER%
The problem turned out to be caused by the proxy configuration on the SCVMM server. In order to reset the proxy configuration I opened an elevated command prompt and ran “netsh winhttp reset proxy”. I was then able to re-install SCVMM successfully.
This solved my issue, damn winhttp proxy!!!!!! if it hadn’t been for this post I probably would still be looking for a solution. Thanks so much! Your a legend!
Same here, searched hours for a solution!
Didn’t solve mine, I have direct access. Still searching
didn’t solve mine. I have direct access, no proxy.
