Dynamic DNS in Win2K

Can someone offer a simple explanation of what is meant by "Register
this connection's address in DNS" under the DNS tab in Advanced TCP/IP
Properties.

According to the help (aka '?' in the top right corner):

"Specifies that the computer attempts the dynamic DNS registration of
this connection with the full computer name..."

What "dynamic DNS registration"? Where is that happening?

My computers are on a peer-to-peer LAN and therefore their IP
addresses are unroutable outside the LAN. Why would the computer want
to register unroutable addresses in some kind of WAN DNS?

Please explain. Thanks.

When setting up a Win 2k domain a DNS server for the Win 2k domain is
required. This is not the ISP's DNS but a DNS server that is usually sitting
on your network set up specifically for your AD domain. Having this box
enabled on the client computer, and pointing the client computer to your AD
DNS server for DNS will register the computer's IP address and name on your
AD DNS server. You will have a DNS zone with all your domain computers
registered.

You should not enable this box if the computer is pointing to a DNS server
not in your control or in the control of your company unless you have talked
to the owner of that box first.

So this applies to Win2K domains, not workgroups (peer-to-peer).

The only DNS boxes I know of are the ones provided by the ISP, for
which I have two addresses entered into the DNS section of
TCP/IP|Advanced|DNS.

But my machine is connected to a NAT router using an unroutable
address. So how would my computer be able to register such an address
on the ISP's DNS box?

For the most part yes. In a work group you can point them to your ISP's DNS
server so they can get Internet access, just don't have them try to register
with their box.

That is how it should be with a workgroup.

It probably would not be able to, but with that box enabled it would keep
trying.
One way to set up a domain that has Internet access would be to have a Win
2k server with 2 NICs. One would have a private IP address serving your LAN
and the other would have a public IP address given to it by the ISP. This
NIC would have to have the "do not register this NIC in DNS" setting
enabled.

I appreciate the time you are taking to provide an explanation.
However, I must admit total ignorance (or near total ignorance) when
it comes to this issue.

Could you please elaborate - or provide a link to a tutorial that will
make this clear, one that is written in human-readable format and not
MS Speak.

In particular what do you mean by ", just don't have them try to
register with their box" ? How would I do that, assuming I wanted to?

So what I think you are recommending is to uncheck that box if you are
using a Workgroup (peer-to-peer) network, because it is not doing any
good.

2k server with 2 NICs. One would have a private IP address serving your LAN

I am only interested in peer-to-peer networking in Win2K.

In a workgroup setting you point all your client computers to the ISP's DNS
servers. Don't check the box that says "register this connection in DNS".
This setting when enabled will try to register the IP address and computer
name with the DNS server listed on that computer (your ISP's DNS server).

Use this setting in a domain environment (which is why *most* people buy Win
2k server) don't use it in a work group.

You can google Dynamic DNS and see what you get. I didn't see anything that
applies to the way MS uses dynamic DNS in Win 2k.
