  • Make sure the service is set to Automatic. More Info MS KB311504
  • Make sure that SYSTEM has Full Control over the following registry key (Use Regedt32.exe):

    [HKEY_LOCAL_MACHINE /SYSTEM /CurrenControlSet /Enum]

Note in WinNT4 this service only provided some wannabe PnP, which mostly works when installing dialup modems.
