OCS/Lync Servers and Users Gathering fails with error: "WMI query select * from MSFT_SIPFederationPartnerTable failed while doing Federated Edge Server discovery: IDispatch error #3600". No Other information is properly gathered from the Pool.
This can be caused if the Service account is able to authenticate against an edge server, but unable to establish a connection via WMI.
Use a tool like the Native WBEMTest.exe bundled with Windows to troubleshoot and resolve issues connecting to WMI on this server.
Disable the Local Service Account on the Edge Server. If Authentication fails the Servers and Users gathering will gracefully move on to the next server.
Enhancement Request TF00195162 has been submitted for consideration in a future version of MessageStats
