1.8 Vendor-Extensible Fields

The Distributed Link Tracking: Workstation Protocol does not define any vendor-extensible fields other than fields that contain globally unique identifiers (GUIDs), as specified in [MS-DTYP] (section 2.3.4.2), and UNC names. The methods for generating GUIDs are as specified in [C706].

This protocol uses HRESULTs, as specified in [MS-ERREF] section 2.1 and discussed in HRESULT (section 2.2.1). Vendors are free to choose their own values for this field, so long as the C bit (0x20000000) is set, indicating that it is a customer code.
