Cannot start Null service

Hi, 

 

Any suggestions on what path is missing here?


sc start Null

SC StartService Failed 3:

The system cannot find the path specified

  • Update: I think the path here was referencing the environment variable for SystemRoot. Adding the missing values in seems to have resolved the issue. Make sure to also check the registry for the null service:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Null
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\DOS Devices
     

    After saving the change, you may not see immediate effect. Reboot to force processes to reload the variables.
