Upgrading PDC, but we use ISP's DNS

[bobk]

I want to upgrade our single NT domain to Win2K Active Directory. We have
a registered internet domain name but we use our ISP's DNS server and the
ISP hosts our external web site. Also, our NT domain name is the same as our
registered internet domain name. (e.g., domain name = "ourco" & internet
name (on our ISP's DNS server) = "ourco.com". So, after I've upgraded our
PDC, in AD Install wizard, should I select "new domain". I'd like the AD
domain name to be the same as our NT domain name (ourco) but would that
somehow conflict with the DNS server at our ISP? Our network includes
external IP addresses. I'd appreciate any direction that anyone can give
me.

It won't conflict with anything, although you do need to be conscious of
this when adding/changing your public name server records.

Because you'll now have an internal zone--call it company.com--your internal
clients will no longer be forwarded to your ISP's DNS to resolve company.com
queries. Instead, your internal DNS will answer for them. As such, you'll
need to add your public host, MX, and other records to the zone file on your
internal DNS, so that internal clients can find those systems by name.
