DNS MP External Resolution Monitor always in a critical state?

This is a problem in the 6.0.6480.0 version of the DNS MP.

This MP includes a monitor to inspect the DNS server’s ability to resolve external domains.

The problem is – that the moniotr defaults to inspecting “www.microsoft.com” when it should use a base domain, like “microsoft.com”.

 

You will find all of your DNS servers in this state – if you dont override it.  This is true for 2003 and 2008 servers:

To resolve this – simply override the monitor, for ALL OBJECTS OF TYPE, and change the Host string from “www.microsoft.com” to “microsoft.com”.  If your DNS servers cannot resolve external addresses by design – disable this monitor.

That's because the "querytype" is 'NS'. You can even leave the "host" string as it is and change the querytype to "A" instead ;-)

I've changed the value to "microsoft.com" as you mentioned. Applied to all objects of type DNS. It worked for a week then the DNS External Res Monitor alerts came back. Weird.
