Symptoms

Example 1:

Host Shows Needs Attention status in SCVMM console and trying to refresh the host errors out with:

Error(2910)
VMM does not have appropriate permissions to access the resource on the Host1.local
server.
(Access is denied (0x80070005))

Recommended Action
Ensure That Virtual Machine Manager has the appropriate rights to perform this action

Example 2:

         When we try to add new host in SCVMM will get below error

 

        A lot of evidence pointed to WMI issues on the host.

Net Mon Trace Details:

Net Mon trace also showed (packet going from host to VMM server): HTTP:Response, HTTP/1.1, Status: Unauthorized,URL: /wsman using Multiple Authentication Methods, see frame
details. However, the Net Mon trace also showed an odd communication that was happening between the host and the VMMserver. The packet sequence No’s are changing sent and received. There is
something intercepting the communication between the host and VMM server that caused this issue.

Http: Response, HTTP/1.1, Status: Unauthorized, URL: /wsman Using Multiple Authetication Methods, see frame details
ProtocolVersion: HTTP/1.1
StatusCode: 401, Unauthorized
Reason: Unauthorized

 Cause

There were Riverbed devices at each location that were optimizing traffic between VMM server and host.

 Resolution

Riverbed Devices needs to be modified to pass-through (exclude) all communications between the SCVMM server and hosts.
