Exchange 2010 CAS WMI problem




Has anyone had any success with connecting to an Exchange 2010 CAS server to query WMI? I keep getting the dreaded 800706BA error. PRTG staff has not been helpful, they blame Microsoft (typical). I am able to connect with other MS and 3rd party tools to WMI on these servers so it can't be the servers. The HT and MBX servers do not have this problem.

Thanks in advance for any insights!

just to explain why we are not taking the blame in this case.

PRTG asks the WMI system of Windows to open a connection to host x with the credentials y. This either works or it does not - with Windows returning an error from a vast list to PRTG.

800706BA is one of those errors.

As it comes from a deeper system level where PRTG has no chance to interfere (neither in a positive nor in a negative way), so it might be a misconfiguration in one of the many, many DCOM/WMI policy/access settings on either the target computer or the system PRTG is running on.

Are you able to connect to the target server with our WMI Tester (running on the same computer as PRTG's probe)?

The main difference between WMI Tester (and other tools) and PRTG's probe is that the probe is running as a service under the computer's System Account (as opposed to the tools which run as interactive processes under a User Account). So there might be some clue as where to look.

Kind regards, - Volker
