After upgrading from vCenter 4.1 to 5.1 we get the following error from the vSphere client when searching for guests.
"Login to the query service failed
The server could not interpret the communication from the client. (The remote server returned an error: (403) Forbidden.)"
(Screenshot of error also attached)
The problem is the same as http://communities.vmware.com/thread/400726
The fixes did not work for us.
We did reinstall VC but also done this on another upgrade and got the same problem.
One thing we have noticed is if you authenticate to the webclient then go back into the full vSphere client it works?????
Anyone seen this before or know what is happening?
