Dynamic DNS Update Option Sent to DHCP Server Even If Disabled Globally (263550)

The information in this article applies to:

Microsoft Windows 2000 Server
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Professional

This article was previously published under Q263550

SYMPTOMS

Windows 2000-based clients that are using Dynamic Host Configuration Protocol (DHCP) may not receive IP addresses from non-Microsoft DHCP servers that do not recognize dynamic DNS update option 81. Disabling this option globally by setting the following value to 1 does not work:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DisableDynamicUpdate

This setting works correctly as a per-interface setting.

CAUSE

This behavior occurs because of a problem in the DHCP client service. It sends the dynamic DNS update option to the DHCP server whether or not you have disabled it globally.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

WORKAROUND

To work around this behavior, set the option on a per-interface basis by clicking to clear the Register this connection's address in DNS check box on the DNS tab in the Advanced TCP/IP Settings dialog box for the interface.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 2.
