DDNS updates (including WINS registrations), static updates, and Active Directory registrations are handled by the DHCPClient service since Windows 95 through all versions of client and server since. The DNSClient handles caching (in a method somewhat akin a very broken caching-only nameserver) only. You can disable the DNSClient service with no ill effect at all (actually, it will probably improve things significantly, if you have a local non-Windows caching recursive DNS to use). You cannot disable the DHCPClient service, however, without breaking DDNS updates, static configuration, and Active Directory. --- () ascii ribbon campaign against html e-mail /\ www.asciiribbon.org
