A "Generic failure" error is seen accessing DNS WMI classes such as "MicrosoftDNS_Zone"

You may see a "Generic failure" error when trying to access DNS WMI classes in the root\MicrosoftDNS namespace such as "MicrosoftDNS_Zone".

In the XIA Configuration Client the error displayed is for example
The DNS service agent encountered an exception when 'Reading forward lookup zones'. Generic failure.


This problem can be caused by a problem with the DNS WMI provider.


  • Ensure you have a full backup of the server
  • Open a command prompt as an Administrator 
  • Enter the following command changing the drive letter and path if required
    C:\Windows\System32\wbem\mofcomp C:\Windows\System32\wbem\dnsprov.mof

  • Scan the DNS service again

For more information on the mofcomp utility please see the following Microsoft web page.
