233-Network control service type

Computer/User Node :

   MACHINE

Policy Path :

   Administrative Templates\Network\QoS Packet Scheduler\Layer-2 priority value

Supported on :

   At least Microsoft Windows XP Professional or Windows Server 2003 family

Help/Explain Text :

   Specifies an alternate link layer (Layer-2) priority value for packets with the Network Control service type (ServiceTypeNetworkControl). The Packet Scheduler inserts the corresponding priority value in the Layer-2 header of the packets. If you enable this setting, you can change the default priority value associated with the Network Control service type. If you disable this setting, the system uses the default priority value of 7. Important: If the Layer-2 priority value for this service type is specified in the registry for a particular network adapter, this setting is ignored when configuring that network adapter.
