DiscoveryMethod (4 bytes): A 32-bit unsigned integer that specifies how the WSD port was initially discovered. Possible values are in the following table.

Name/value	Description
kMulticast 0x00000000	The WSD port was initially discovered by using multicast discovery.
kDirected 0x00000001	The WSD port was initially discovered by using directed discovery.

GlobalID (2048 bytes): A null-terminated Unicode string which, if DiscoveryMethod is kMulticast, specifies the PKEY_PNPX_GlobalIdentify of the device attached to the WSD port; otherwise, this field MUST be a NULL pointer.

RemoteURL (2048 bytes): A null-terminated Unicode string which, if DiscoveryMethod is kDirected, specifies the URL of the device attached to the WSD port; otherwise, this field MUST be a NULL pointer.
