Win2K DNS, System Events, logon events

By johnnyextreme ·
I have auditing of failed logons on a Win2K server which is PDC. Security Log is huge with failed logons which match the DNS registration/deregistration failures in the System event log. System events are all like this:
Registration of the DNS record 'blah blah' failed with the following error - DNS server unable to interpret format.
One failure for each default record in DDNS. Failed logons are from the "real" dns server which is ISP provided or blackhole.isu. I don't have a pure Win2K network and don't use this servers DNS for resolution - how can I stop this?

Ah, let's see...One Win2K server, as a PDC? Not in Native mode? Not a Win2K DNS server? Upgrade the DNS server to win2K DNS if it isn't already. Just be sure you're using an internal Win2K DNS server for your Win2K server. If you're going to Win2K, do it ALL, especially be sure your DNS is Win2K since Win2K relies upon it an it's dynamic updates heavily...

I don't know why any of our machines are Win2K, but they aren't all Win2K. I can't upgrade our ISPs DNS server, or Blackhole.isu for that matter and bringing DNS inhouse is not feasible at this time. I'd rather this PDC didn't try to do DNS. Surely there are hundreds of companies with the same situation - a Win2K PDC with an ISP providing DNS. Do I want to stop this server from trying to talk to other DNS servers? Is something configured wrong?

A Win2k server is two things... A BASIC server... or a server that is converted to ACTIVE DIRECTORY. IF this server has AD configured...your screwed if it can't be the DNS too. The only thing you can do is make sure that the AD is not active. Just server and then things will work for you in a mix-match environment. If you are a AD guru... you would now how to manipulate the DNS in the WIN2K box to work with the rest of the network and still be active with the ISP.
Otherwise, try to have ONLY SERVER going, which MEANS you can not have this box as a PDC without it's DNS active everywhere.

What's the deal w/ upgrading the ISP to win2k? Do an upgrade check on it to see if it qualifies. UNIX, PC & DEC Alpha's quialify for machines...just check the hardware and software w/ MS check utility.

So my choices are 1. become an AD guru, or 2. convince our internet service provider to switch to Windows 2000. Even if this Win2K PDC was the DNS server for all the workstations it would have to talk to other DNS servers, and it seems this is whereI have the problems: DNS Server unable to interpret format (the dynamic updates?), and the logon failures from our Internet provider's DNS to the Win2K machine.

Ok... now that I have a better understanding..and DON'T ask me why the heck I thought that the ISP was in-house. I guess I was tired. I have the BIG picture now and I hope to finally take your 300 POINTS. Anyways, back to your issue:

You PDC must be configured to be the MASTER DNS on the entire inhouse network. Your ISP's DNS will function through DNS FORWARDERS. I won't get into the NITTY-GRITTY here...but, I hope that this LINK will give you EVERYTHING that you need to finally get this cheese out of your hair.

I was trying not to be rude, so I spelled out I.S.P. just to make sure you knew what I was saying. I've been over this KB article and did make some changes to the DNS configuration, none of which stopped the system errors or the logon failures. I'm closing this thread, but could anyone please e-mail me about why this Win2K computer is trying to log onto the ISP's DNS server? There are like 50 of each of these errors every hour, which makes it hard to find actual logon failures.

I stopped this by pointing this DNS server to itself as the only DNS server in TCP/IP properties and specifying Enable NetBIOS over TCP/IP, uncheck Register this connections address in DNS.
