Hello Everyone,
I am looking for some advice with problems that I have been having. My SBS 2003 event log is showing DNS errors.
Those errors where as follows.
1) The DNS Server was unable to complete directoy service enumeration of zone company.local. This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it. Check that Active Directory is functioning properly and repeat enumeration of the zone. The extended error debug information (which may be empy) is “”.
2) The DNS Server was unable to complete directoy service enumeration of zone 0.168.192.in-addr.arpa. This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it. Check that Active Directory is functioning properly and repeat enumeration of the zone. The extended error debug information (which may be empy) is “”.
3) The DNS Server was unable to complete directoy service enumeration of zone ..

4) The DNS Server was unable to complete directoy service enumeration of zone _msdcs.company.local This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it. Check that Active Directory is functioning properly and repeat enumeration of the zone. The extended error debug information (which may be empy) is “”.
5) The DNS server has encountered a critial error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is “”.
Prior to the above errors which surfaced today, I had only one error which was with reference to a Host Records A replciation issue. I have changed the server to listen to its own IP address only. It was listening to its own plus another IP address that related to a secondary NIC that is now disabled.
There are so many errors as listed above I really need help. To get a clearer picture about what those errors where I ran netdiag (failed to run) and dcdiag. The reports came back with a fair few points of information.

Performaing initial setup:
Done Gathering initial info.
Doing initial required tests
Testing server: Default-First-Site-Name\COMPANYDC01
Starting test: Connectivity
COMPANYDC01’s server GUID DNS name could not be resolved to an IP address. Check the DNS server, DHCP, server name, etc.
Although the Guid DNS name (xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx._msdcs.company.local) couldn’t be resolved, the servername (COMPANYDC01.company.local) resolved to the IP address (192.168.0.16) and was pingable. Check that the IP address is registered correctly with the DNS server.
…………………………COMPANYDC01 failed test connectivity.
Testing Server: Default-First-Site-Name\COMPANYDC01
Skipping all tests, because server COMPANYDC01 is not responding to directory service requests.
I get the general idea of whats gone wrong, I just really need the advice and help to put it all right. All your input is welcome and if I can suuply you with more details then let me know. COMPANYDC01 etc etc is what I have changed because of this being a public post on a forum.
Thanking you all in advance
Yan.
