If you need a DHCP server but don't wish to install Active Directory services, simply add a registry key here:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\DHCPServer\Parameters
with type and value:
Name: DisableRogueDetection Type: REG_DWORD Data: 0x1
And restart the server (only restarting the service will not help)
