Hi guy's. My company runs a WInNT domain and we would like to migrate to Windows 2000. We have our domain name registered and hosted on some web-host's server. How can we still use the "mycompany.com" domain for our Windows 2000 active directory ? Would would have to create a subdomain or use something like split-dns?

I'm a little confused. Please help.

As your company's internal DNS namespace is seperate from the public Internet's DNS namespace, you can go ahead and set up internal DNS servers for your domain.

The Minasi article and book referred to above was helpful to me, too - but I've found there is some disagreement about this. What I have found that works for me:

1. Set up internal DNS server(s) and configure a DNS zone using your registered domain name.
2. Set up a reverse lookup zone also.
3. On your internal DNS server, enable forwarders and enter your external ISP's DNS servers as the forwarders.
4. Be sure that you disable recursion - I think the Minasi article refers to this too.
5. Do NOT publish your internal DNS servers on the Internet unless your DNS server is going to be the registered host for your domain. This is usually where everyone gets confused. As long as your ISP is actually hosting your domain, name resolution for external hosts trying to find your domain will be done by your ISP's DNS servers, not your internal ones.

Your internal workstations should be set to use your internal DNS server(s) exclusively. By virtue of using your ISP's DNS servers as forwarders, your internal DNS servers will go out to the ISP to resolve IP addresses that they don't have either in their name cache or registered as local hosts.

Hope this helps!

As I can understand your domain is hosted somewhere outside your company, so there's no use to publish YOUR server records to internet. (Answer this question: your web server is using a public or private IP address?)
Set up a win2k server, with a PRIVATE ip address, setup DNS in THAT server matching mycompany.com, define here your servers adding an "A" records (server1.mycompany.com), where server1 is the NAME of the computer, an so on.

Next configure your clients to reslove names up to what dns ip address?,
-The private one!, so when you type: "ping.exe server1.mycomany.com", the computer looks where is the DNS ip address pointing to (in this case, your win2kserver with DNS),a dns server, next: does this DNS holds the "name space" for "mycompany.com" domain?
Yes-, next: Is there an "A" record whose name is "server1"?
Yes, next: Give me it's Ip address
Result: Name solved. This is the way dns works!!!

If your WKS are currently pointing to a DNS which belongs to internet (in order to browse & navigate internet, usually the ip is provided by your ISP), you simply need to add a secondary DNS ip address, placing FIRST your DNS and second the internet one server Ip address.
Hope it's clear & helps!!
