//              04/??/97        JerryK  Stopped updating these comments since

//  Notes:
//
//      This sample OCM component DLL can be the component DLL
//      for multiple components.  It assumes that a companion sample INF
//      is being used as the per-component INF, with private data in the 
//      following form.
//
//      [<pwszComponent>,<pwszSubComponent>]
//      Bitmap = <bitmapresourcename>
//      VerifySelect = 0/1
//      VerifyDeselect = 0/1
//      ;
//      ; follow this with install stuff such as CopyFiles= sections, etc.

// Routine Description:
//    This funcion sets the original, current, and final selection states of the
//    CertSrv service optional component.
//
// Return Value:
//    SubcompOn - indicates that the checkbox should be set
//    SubcompOff - indicates that the checkbox should be clear
//    SubcompUseOCManagerDefault - OC Manager should set the state of the checkbox
//                                 according to state information that is maintained
//                                 internally by OC Manager itself.
//
// Note:
//    By the time this function gets called OnOcInitComponent has already determined
//    that Terminal Services is not installed. It is only necessary to determine
//    whether Terminal Services is selected for installation.
