I am running a Windows Server 2003 ent ed Webserver on my home network, I have 5 computers on it. My ISP has been having trouble with their DNS servers as of late, so I was wondering if it would be possible to setup server 2003 to be my DNS server. So that I can resolve external IPs with it and all that. I've looked around and all I see is information on how to set up a DNS server to resolve local IPs, but all I have are 5 computers so I don't think that is necessary. Is this possible? and how would I go about doing this?

You can use your Local DNS server to resolve local IP's but for it to provide resolution outside the local zone you have to enable forwarding on it. In order to make this work, enable forwarding on the DNS server and have your clients point to the internal DNS server. You may encounter problems connecting internally to your web site or possibly externally as well if you change your present DNS configuration. So be aware of that before you begin making changes. I'm not web site admin so hopefully someone else will come along that will be better equipped to help you. But I do have plenty of experience installing/maintaining servers and domains and the above is the preferred method for configuring DNS within a domain. You could help us help you by telling us how your DNS is presently configured.

Take a look at TreeWalk (http://ntcanuck.com) it is a free full DNS server, designed for low traffic, ie home networks.
