While it shouldn’t be necessary, sometimes you find that you need to get around Windows’ process of checking with AD to see if it is authorised to service DHCP requests. This works in 2000, 2003, and should work in 2008 but has not been tested.
To disable this check, create this registry key
KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DHCPServer\Parameters
\DisableRogueDetection
and set the value to 1, and reboot the server.
The DHCP service should start upon reboot and service requests.
For Server 2008, there is a much slicker way to do this…not sure if it works in 2003; I don’t have a server to test. Open an administrator cmd prompt, then
reg add HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\DHCPServer\Parameters /v DisableRogueDetection /t REG_DWORD /d 1 [enter]
and then reboot. KB949530 here.
