Name System (DNS) servers. The typical points of failure in the update process
and how to diagnose them are also described.

HOW TO: Configure DNS Dynamic Update in Windows 2000
The dynamic update process can be broken into five basic
- A Windows 2000-based client queries its configured DNS
server to find the authoritative name server for the domain name it is
attempting to update.
- The local name server of the client performs the standard
name resolution process to discover the authoritative name server. This DNS
server must respond to the client query with the start of authority (SOA)
record and the Internet Protocol (IP) addresses of the name servers that are
authoritative for the zone that the client queried.
- The Windows 2000-based client sends a dynamic update
request to the authoritative DNS server for the zone that the client is
attempting to update.
- The dynamic update request of the client may include a list
of prerequisites that must be fulfilled before an update can be made. The types
of prerequisites include:
NOTE: Refer to Requests for Comments (RFC) 2136 for a full description
of these prerequisite types.
- The resource record set exists.
- The resource record set does not exist.
- The name is in use.
- The name is not in use.
- The authoritative DNS server checks whether the
prerequisites have been fulfilled. If they have, the DNS server performs the
requested update. If the prerequisites have not been fulfilled, the update is
not successful. In either case, the DNS server replies to the client,
indicating whether the update had been successful.
Updates can be unsuccessful for several reasons:
