DNS error message in dcdiag.exe

G'day guys,

Interested whether the following is of concern.   CAN01 is the domain controller

Output from dcdiag:

Doing initial required tests

   Testing server: Default-First-Site\CAN01
      Starting test: Connectivity
         The host eaee4167-2439-455f-bd69-e751a2f65eec._msdcs.fys.car.dsn.mil.au
 could not be resolved to an
         IP address.  Check the DNS server, DHCP, server name, etc
         Although the Guid DNS name
         couldn't be resolved, the server name (CAN01.fys.car.dsn.mil.au)
         resolved to the IP address ( and was pingable.  Check
         that the IP address is registered correctly with the DNS server.
         ......................... CAN01 failed test Connectivity

The record it's troubled by lives under the _msdcs folder in your Forward Lookup Zone. Can you see if it really exists? It'll look like this if it exists:

eaee4167-2439-455f-bd69-e751a2f65eec    CNAME    CAN01.fys.car.dsn.mil.au

If it doesn't, does anything exist for CAN01 in there?
