Windows 2003 SBS: DNS error 4007 always in logs...

Hi All,
Recently, EE experts helped me get my DNS Server working like a charm. There's one issue that remains, that, although I've not found any problems associated with it, probably needs attention.

Can someone advise me as how to resolve the issue related to the 2 DNS Error log entries below. Both of these errors very similar and can be produced at will by restarting the DNS Server service:

--== ERROR #1 ==--
Event Type:      Error
Event Source:      DNS
Event Category:      None
Event ID:      4007

Time:            5:49:41 PM
User:            N/A
Computer:      SERVER2003
Description:
The DNS server was unable to open zone oaswtn.local in the Active Directory from the application directory partition DomainDnsZones.oaswtn.local. This DNS server is configured to obtain and use information from the directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and reload the zone. The event data is the error code.

Is this a single Domain Controller Network? If so, is the network TCP/IP configuration, pointing to itself. The TCPIP config should have only itself in its DNS configuration.

Additionally, if the above is not applicable to yoru environment, does you domain have a _msdcs subfolder in the DNS config for oaswtn.local, and dos it contain a CNAME record with the server name in it?

Yes. Single DC in the network. The server itself is the only referenced DNS setting (i.e., bot adapters have 192.168.16.1 as the DNS server). Ipconfig:

Ethernet adapter external:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.0.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.254

Ethernet adapter internal:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.16.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :

Please do an IPCONFIG /ALL and post the results.

Here is another KB article that applies to your situation as well, especially with the PPP adapter. Are you running ISA on this server as well?

you should ahve something like this

Ethernet adapter internal:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.16.1
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1
DNS servers........................: 192.168.16.1

then in you dns console go to the properties of your dns server and on the forwarders tab enable forwarding to your ISP's dns server.

If the server is Multi Homed and the Internal interface is on a single subnet then the Gateway should not be on the Internal adapter. Whichever interface is required to respond to machines that are not on the interface local subnet, then that is the one which receives the gateway. In this particular configuration the Gateway should most likely be on the external interface. Multiple adapters can and will cause lots of confusion.

J's right. Here's a good reference for 2 nic setup: http://www.smallbizserver.net/Default.aspx?tabid=52

no change in error log being reported when machine (or service) restarts. Likewise, still no obvious problems that I can find either, aside from the logs.

Thanks for your help, J.
