Active Directory Interview Question:

How Windows 2000-Based Computers Update Their DNS Names?

Submitted by: Administrator

Windows 2000 computers try to dynamically register host address (A) and pointer (PTR) resource records. All computers register records based on their full computer name. Dynamic updates can be sent for any of the following reasons or events:
★ An IP address is added, removed, or modified for any one of the installed network connections.
★ An IP address lease changes or renews. For example, if you use the ipconfig /renew command.
★ You use the ipconfig /registered command to manually force a refresh of the client name registration in DNS.
★ At startup time, when the computer is turned on.
When one of these events triggers a dynamic update, the DHCP Client service (not the DNS Client service) sends updates. This process is designed so that if a change to the IP address information occurs because of DHCP, corresponding updates in DNS are performed to synchronize name-to-address mappings for the computer. The DHCP Client service performs this function for all network connections used on the system, including connections that are not configured to use DHCP.
