Had this error occur in my Hyper-V lab after playing with WinRM GPOs. After removing the GPO because SCVMM is a finicky pain – I was still receiving this error when attempting to create a new VM:
An internal error has occurred trying to contact the lab-hyperv1.lab.int server: : .
WinRM: URL: [http://lab-hyperv1.lab.int:5985], Verb: [INVOKE], Method: [CreateDirectory], Resource: [http://schemas.microsoft.com/wbem/wsman/1/wmi/root/scvmm/FileInformation]
Invalid Signature (0x80090006)
Recommended Action Check that WS-Management service is installed and running on server lab-hyperv1.lab.int. For more information use the command "winrm helpmsg hresult". If lab-hyperv1.lab.int is a host/library/update server or a PXE server role then ensure that VMM agent is installed and running. Refer to http://support.microsoft.com/kb/2742275 for more details.
Here’s how to fix this:
- Remove the affected Hyper-V hosts from SCVMM
- Open Certificate Management (Computer) and make sure you don’t see certificates for the Hyper-V hosts in the ‘Trusted People’ store
- Re-add the Hyper-V hosts
You should now be able to create new VMs.
