I understand that the DNS on my server should actually be my internal DNS, so I am wondering where I should actually put the external DNS information in my DNS server.

You should use your external DNS server as forwarders, if you use them at all.

Microsoft DNS can resolve using root hints, so if you haven't configured forwarders that'll be what it's doing now.
