DNS / DSL Issue with Administrative Tool

By tobrahs ·
I am rolling out a domain using one Windows 2000 Server as DC and one member server, the workstations are Windows 2000 Pro. We use DSL service to connect to the internet. I find that in order to connect to the internet I must configure TCP/IP settings so that the DSL IP address is in the Preferred DNS Server and the Windows 2000 Server is the Alternate DSL Server. Sure we can log onto the domain and access the internet but I am unable to use Administrative Tools or MMC components that connect to the server. In order for me to use Admin Tools I must switch the DNS IP address to the Windows 2000 Server. When I do this I am unable to access the internet. Apparently there is a DNS issue, could someone point me in the right direction?

DNS / DSL Issue with Administrative Tool

Your internal DNS server should be the first server listed, followed by the ISP DNS.

Do you connect using a router? If you're using a router, you'll need to specify it's IP address as the default gateway for your clients.

If you're using your w2k server as a router (with 2 NICs), then the NIC that's making the internet connection will be the default gateway.

If I list my DNS server as the Preferred DNS server I can not reach the Internet. The DSL router is specified as the gateway.

What I would do as well is to setup your internal Windows 2000 DNS to use the DSL DNS servers as forwarders. This would solve your MMC problem.

I found that my DSL service is providing DNS. I am unable to use the DSL DNS servers as forwarders due my 2000 server being a root server. Any suggestions?

Interesting issues. Not being able to access Administrative tools from the control panel or open a MMC on the DC is not something I've run across except in a bad install.

As far as not being able to access administrative tools or open a MMC, areyou trying this remotely or directly on the server? Are you trying to access the server remotely via terminal services remote administration?

As far as your internet connections how about a little more info such as: are you using a router betweenthe modem and server? Are you using 1 or 2 NIC's? What does the DSL ISP provider tell you when configuring your NIC & internet browswer. If you use a router between the DSL modem and the server, what does the router manual say as far as configuring your NIC & internet browser?

On a straight DSL modem to server connection, unless the ISP provider specifies including their DNS servers in the NIC properties, most will tell you to use automatic discovery. For your IP assignment, most if not all, ISP DSL providers use DHCP to provide residential DSL service and will have you use automatic discovery.

Problem solved - I had not removed the "." zone which was making DNS think it was the root server. I then was able to set up forwarders to the DNS IP addresses that are set in my DSL router. I was not able to use MMC or Administrative Tools untilI uninstalled Active Directory and re-installed it. I then uninstalled Administrative tools on the workstation and reinstalled it which took care of that problem. By being able to set up forwarders I am now able to just enter the IP address of my DNS server in the Preferred DNS Servers property box. THANKS FOR THE RESPONSES!
