- The DNS server must support RFC 2052, SRV RR.
- The DNS must support RFC 2136, dynamic update protocol.
Of course, if you have an existing DNS and simply want to incorporate the use of Active Directory, you may wish to take the easier route of simply creating a separate zone for the internal machines that AD will be supporting and then delegate that zone to an internal Windows 2000 DNS implementation. As long as you are not dealing with 10,000 users/workstations you could most likely use the domain controllers as your DNS servers. Take a look at MS KB 301191, Integrate DNS with existing DNS infrastructure if Active Directory is enabled in Windows 2000.
