Unique identifier by which the server identifies the client.
PROPVARIANT type (vt)
The MFNETSOURCE_CLIENTGUID constant defines the GUID for the property key. The property identifier (PID) is zero. To set this property on the network source, pass an IPropertyStore pointer to the source resolver. For more information, see Configuring a Media Source.
If not set or set as GUID_NULL, Microsoft Media Foundation generates an anonymous GUID per session that ensures the user's privacy.
