ERROR_ACCESS_DENIED for deleting services

Running a program, that loads and unloads driver as service. Works fine on win2k but ROS reports ERROR_ACCESS_DENIED when trying to delete the service.

When trying to delete a service, believe the wrong thing is checked here.
if (!RtlAreAllAccessesGranted(hSvc->Handle.DesiredAccess,
STANDARD_RIGHTS_REQUIRED))

Using only START_SERVICE + STOP_SERVICE + DELETE works in win2k.
Should be
if (!RtlAreAllAccessesGranted(hSvc->Handle.DesiredAccess, DELETE))

Though this fixes the issue with rights, there are other problems with service removal.
