I have a new install of a Windows 2000 server and continue to receive the warning message in the event log: Dynamic registration or deregistration of one or more DNS records failed because no DNS servers are available. I have reinstalled, auto configured manually configured and cannot resolve it. It appears to be a client error. I located an article at MS tech sight Q260910 which stated to install SP1 which I did and this did not resolve the warning. I would like to clear up this warning before I let my users attach to it. It is the only 2000 server in my network running DNS and Active Directory. Any help provided would be greatly appreciated.

Thanks for the info, I reviewed these articles, tried what was recommended but still receiving the message. Would you have any other ideas that I may try? Any information you could provide would be greatly appreciated.

Make sure that your Win2K DNS server is configured for Dynamic Updates. Active Directory requires this, so it can add its SRV (service) records to DNS. You will want to right-click your forward lookup zone and set it there. Make sure the DNS server points to itself and the AD server has this DNS server listed as its only DNS server. This should clear up the NETLOGON events.

Thank you for your response, When I configure DNS for dynamic updates, changing from Only secure updates to YES, I still receive the warning plus several new Errors appear in the DNS folder of the event log. How can I check to be sure the DNS server is pointing to itself and the AD server has this server listed as it only DNS server as you stated in your response?

I want to add to your problem.
I have installed four Windows 2000 Servers during past month and on each of them I am getting error mesage 5774 (Netlogon registration) about the same problem you stating in your description. MS is not specific on how to troubleshoot this problem.
I installed SP1 and read a lot of info about this issue.
Any suggestions?
Anybody?

WE were getting the same problems. If memory serves me right we changed our DNS settings to point to our DNS server which is located off site.
We also had to copy our Netlogon.dns
(%system root%\system32\config) file to our DNS server.
Hope this gives you some insight.
It worked for us.

Thank you for your response but the machine I am receiving the error on is my DNS server as well as running active directory, and as far as I can tell the machines dns settings are pointing to itself.

Just resolved this issue myself yesterday after working on it for months. Configure your TCP/IP with your loopback address 127.0.0.1 as the preferred DNS Server and your acutal IP address as the alternative. Make sure you select to register this connections address in DNS. IN the DNS console configure a Primary Zone Forward Lookup Zone and a Reverse Lookup Zone. When the Zones are created, right click the Reverse lookup zone and under ACTION creat a new POINTER Record and insert the last three numbers of your IP address in the Fourth Octet, and type in your fully qualified Domain Name ie. Server01.domain.local. (make sure you include the . (dot) at the end. Reload the zones and do nslookup at the command prompt your reply should be defauft server local machine, follow in the active mode with ls domain.local (where domain is your domain name and local is your dot zone) your response should be the "A" record for your server. Finally ping yourself ie. ping computername, the response should be reply from computername.domain_name.zone.
Good Luck

Thank you for your response. I believe I have my server configured as you instructed above but I am still receiving the netlogon 5781 error. I did allow the active directory wizard to configure my forward lookup zone for dns but I created the reverse zone as you instructed in your response. Wehn I run the nslookup commands all looks good when the response is returned and I can ping the local machine name with no problem. The only setting I am unsure of is the "Make sure you select to register this connectins address in DNS" - the only location I have found for this setting is located in the TCP settings within the advanced settings on the DNS tab. There is a checkmark in this location, is this all that is required or in there a need to input more information either on this screen or somewhere else. Thank you again for your response.
