DCDIag error on Windows 2003 Server SP2

DCdiag gives the following error :

Starting test: Connectivity
The host 8e363e9d-1508-4f2a-b038-dc1054dc177b._msdcs.appsoft.accord.com could not be resolved to an
IP address. Check the DNS server, DHCP, server name, etc
Although the Guid DNS name (8e363e9d-1508-4f2a-b038-dc1054dc177b._msdcs.appsoft.accord.com) couldn't be resolved, the server name (blaze.appsoft.accord.com) resolved to the IP address (192.168.1.69) and was pingable. Check that the IP address is registered correctly with the DNS server.

I have followed almost all replies and reviews on this. But I was not able to resolve this issue. Any help would be appreciated.

Thanks
