PROBLEMS WITH DNS

[nakatsue]

Hi,

I have one Win2K server installed in private network (10.0.0.1/254) with AD - PDC and DNS server for private domain name something.local.
When installing AD, the DNS server was automaticly installed and I have not made any configuration changes.

The problem is if I use my ISP DNS in TCP/IP settings I got NETLOGON errors 5781 every two hours.
If I set in TCP/IP settings servers IP like primary DNS server the error is gone but I am unable to get to internet.

I suppose that I have to tell my DNS server to redirect requests for global domains to ISPs DNS servers (am I right?), but I don't know how.
I don't know a lot (read anything ;-) ) about DNS servers and I would like you to give me simple instructions how to configure it.
Updates from ISP to my server should be done and not in other way.

Please do not send me links about Ms KB Q311354, 263091, 244669, 252695, 259277, 257462

Thank you very much for your help!

When you install a domain controller it looks for a DNS server that it could register itself on. It looks like it was not able to do this or find the server, therefore it installed DNS with an AD integrated zone for new domain.
The reason for your authentication errors is because your server needs to point to itself (its own DNS) in order to make use of all AD services that are reliant on DNS
If you need to be able to access your external DNS server (your ISP server), create a root hint (in DNS properties) that points to your ISP's server and not setup your IP properties to point to it. Hope this helps.

You're right about needing to point to your DNS to yourself to get rid of the Netlogon errors. And easier than configuring root hints would be to set up your ISP's DNS servers in the Forwarders tab in your DNS settings. Your server won't do any of its own querying footwork on the internet, but will have all its DNS queries handled for it by the ISP's DNS, which is usually going to be just fine.

Creating a root hints if you don't have one isn't always simple for a beginner.
