256986 Description of the Microsoft Windows Registry
SYMPTOMS
After you install Service Pack 2 (SP2) on either your Windows 2000-based Service Pack 1 (SP1) Remote Installation Services (RIS) server or on your stand-alone Dynamic Host Configuration Protocol (DHCP) server (that does not have RIS installed), you may receive the following event message when you restart the server:
CAUSE
This problem can occur because either the RIS or DHCP server is not authorized in your Active Directory.
RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To resolve this problem, re-authorize your Windows 2000-based RIS server in your Active Directory:
- Click Start, point to Programs, point to Administrative Tools, and then click DHCP to start the DHCP snap-in.
- Right-click DHCP in the upper-left corner of the DHCP screen, and then click Manage Authorized Servers. If your server is not already listed, click Authorize, and then enter the Internet Protocol (IP) address of the RIS server. When you are prompted, click Yes to verify that the address is correct.
- Restart the DHCP server.
To resolve this problem on a DHCP server that does not have RIS installed:
- Add the following DWORD value in the registry:
- Start Registry Editor (Regedt32.exe).
- Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Dhcpserver\Parameters
- On the Edit menu, click Add Value, and then add the following registry value:
Value name: DisableRogueDetection
Data type: REG_DWORD
Radix: Binary
Value data: (Hexadecimal) 1, which will be saved as 0x00000001 - Quit Registry Editor.
- After you have added the preceding value, restart the server for the setting to take effect.
NOTE: If you have a stand-alone DHCP server, several new fixes are included in Windows 2000 SP2 for DHCP servers, which may require additional settings.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
With RIS servers, the event ID 1051 has only been observed when you update a Windows 2000-based RIS server with SP1.
