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.


Cause

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


 Resolution

  • 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
