        the options listed below, the services are enumerated.
    type=    Type of services to enumerate (driver, service, all)
             (default = service)
    state=   State of services to enumerate (inactive, all)
             (default = active)
    bufsize= The size (in bytes) of the enumeration buffer
             (default = 4096)
    ri=      The resume index number at which to begin the enumeration
             (default = 0)
    group=   Service group to enumerate
