Attempting to use a SQL monitoring package (Red-Gate) that queries OS metrics via WMI. Running on a Windows 2003 server, I can monitor one server running Windows 2008 R2 but not another. Using webmtest gives the same problems, login failures.
All servers are on the same network segment, no firewalls in between. In an attempt to diagnose the problem, I have elevated the Windows account used to administrator, added it to the DCOM users group, and configured security as wide open as possible in WMI and DCOM as suggested in the following docs:
The monitoring service always fails with 0x80070005 (DCOM ACCESS_DENIED).
Looking for other solutions.
