SUMMARY
Previous versions of Microsoft operating systems that do not support dynamic Domain Name System (DNS) require that a static DNS entry use a static IP address whenever possible. If you upgrade to Microsoft Windows 2000 and your present DNS server is Windows 2000, the IP address stays the same, but the DNS &quot;A&quot; record remains static. However, the static PTR record is converted to a dynamic entry and is subject to the aging process.

MORE INFORMATION
The Windows 2000 Dynamic Domain Name System (DDNS) client does not overwrite an existing &quot;A&quot; record if the IP addresses match. To convert static entries to dynamic entries, use the /AgeAllRecords option in the Dnscmd.exe program:

USAGE: DnsCmd  /AgeAllRecords  [] [/Tree] [/f]  -- FQDN of a zone  -- name or node or subtree in which to enable aging - &quot;@&quot; for zone root OR                  - FQDN of a node (name with a '.' at the end) OR                   - single label for name relative to zone root /Tree     -- force aging on entire subtree of node or entire zone if node not given /f        -- execute without asking for confirmation Additional query words:
