Domain Controller access to Internet through Cable ISP

Posted on 2006-05-29
Last Modified: 2013-11-30
I'm running Win2000 Advanced Server:  I installed a DNS Server and assigned the server a static IP address, subnet mask, and gateway address.  I then ran dcpromo to create  the first domain controller of a new domain tree.  My problem is that now I'm UNABLE to connect to the internet.  I have a VoIP broadband router connected to a cable modem.  I called my ISP provider and they told me that I had to enable DHCP.  When I enabled DHCP I was able to access the internet.  Did I destroy the new domain that I just created since I'm not longer using a static IP?

My goal is twofold:
1.  I want to access remote computers running XP Pro and add them to my new domain.
2.  I want them to be able to access different computers on the network remotely.

    Thay would depends...where did you enable DHCP ? (On the CableModem, router, or the Server (Windows DHCP Server)?). The thing you have to consider is the fact that only one DHCP can exist on your network. If you want to use static IP on your server (so that you can useit as dns server,) you need to Purchase and install a secondary network Card. Once installed, you need to configure one of the cards to be on DHCP (which connects to the internet) and the other one to your static configuration. also, your DNS servers still needs to be configure so that it can forward the requests to the upstram dns server (your ISP's dns serveR). bottom line, make sure you have only one DHCP server, and second, (if your CableModem already assigning IP addresses,) you should set static IPs on that subnet. If you still have problem, you need to give us more inforamtion so we can better understand your network configuraiton.

    One way to do this, install windows 2000 support tools
    then use NetDiag.exe /v     ( ) to get complete status of your network. then you can paste it over here.
