Dynamic dns records not updating
By default, computers that run Windows 2000 and are statically configured for TCP/IP attempt to dynamically register host (A) and pointer (PTR) resource records (RRs) for IP addresses configured and used by their installed network connections.By default, all computers register records based on their full computer name.In addition to the full computer name (or primary name) of the computer, additional connection-specific DNS names can be configured and optionally registered or updated in DNS.RFC compliant dynamic DNS (not DDNS based on external updates like a HTTP channel) can be complicated to troubleshoot.
Windows 2000 provides client and server support for use of dynamic updates, as described in RFC 2136.
See Quick Task: Create Dynamic DNS Host for instructions on setting up the Dynamic DNS Service.
The update client is responsible for sending updates to Dyn Managed DNS whenever a host’s IP address changes.
The Dynamic DNS service must be activated on a host record before it will accept dynamic updates.
The service can be added to an existing A record or it can be added when the A record is created.
