DNS problems 1

[GaryCracker]

I have a Windows 2000 server running DNS and a 3Com office connect ISDN router. To connect to the internet you need to add the IP address of the router in the dns on the workstations.

On Windows 2000 clients, when you add the dns of both the server and the router you cannot connect to the internet. To connect to the internet you need to take out the dns ip address of the server. On windows 98 clients you can add both as long as the router is added first.

Can anyone explain why this is or know of a fix?

Thanks

How do you have your DNS server set up? Did you delete the root "." zone and add the IP address of your ISP's DNS server as a Forwarder? All your clients should only be pointing to your DNS server for resolution, then the server will forward out any requests that it can't resolve to your ISP.

So you delete the "." entry then add a standard primary zone. Then what do you call the zone? "." again as the previous?

Have you got any step by step guides of documentation which will help me.

The isp we are using is 0800dial.com and they use dns 194.176.194.129 and 194.176.194.137.

Thanks

Delete the "." zone. Add a standard primary forward lookup zone using the name of your workgroup and add a .local extension to it. So if your workgroup is called Office, call the zone Office.local . Enter host records in this zone for all of your machines. Then, add the IP addresses you gave above as Forwarders (in the Forwarders tab) which you'll find by right clicking on your DNS servername in DNS manager. On your clients, use only your internal DNS server for resolution.

Thanks for your help. This works fine.

Do you know of a way the dns searches all computers and adds the dns automatically or do you have to manually enter each one.

Thanks

DNS doesn't do that, but DHCP and/or the clients themselves can do it. Make sure you set the DNS server to allow dynamic updates. If you're using DHCP, in the properties of that, you can set it to "Always update DNS...". If you're using static IP, then in the machine's NIC properties, there's a checkbox to "Register this connection in DNS..."

What happens if you remove the router from dns and just use the dns server. Is the router getting you out, so that would be the gateway? Just a question since I don't know the hardware. Glen A. Johnson

Do you know of a way of setting Windows 98 machines to register the DNS automatically as most of them are running this.

Thanks for your help. The above also sorted out a problem i was having running admin tools in 2000 pro to administer the server.

98 clients cannot register themselves, but if you're using DHCP on a 2K server to assign addresses to them, the DHCP server will do it. If you're using static IP on those 98'ers, you're out of luck. Enter them manually...
