    OWA 2007 Monitor Failing
    Version:
    14.0
    Message:

    Hello Community.

    I'm running WUS Premium 14.1.2 and am trying to build a monitor for Exchange 2007 OWA. When I run a test for the OWA part of the Exchange monitor, I receive the following error:

    Error attempting to executing the WQL: SELECT * FROM Win32_PerfFormattedData_MSExchangeOWA_MSExchangeOWA
    Invalid class

    Does anyone have any idea why that would happen?

    Thanks in advance.

      Michael,

      This error indicates that the Win32_PerfFormattedData_MSExchangeOWA_MSExchangeOWA WMI class is not "registered" on your Exchange 2007 server. This can happen if the WMI service starts before the OWA service. Please run the following command in an administrative command prompt window on the Exchange 2007 server and then test the monitor again:

      wmiadap /f

      Ambar,

      I ran the wmiadap /f command from the prompt, and I also restarted the Windows Management Instrumentations servicfe, but I still get the error when running the OWA test. Is there a wait time for the counter to be loaded, or is there something else going on?

      Thank you for your help.
