object is deleted. The cluster transport is also updated if
necessary.
Arguments:
IsSourceNode - Set to TRUE if this node is the source of the update.
Set to FALSE otherwise.
InterfaceId - A pointer to a unicode string containing the ID of the
interface to delete.
Return Value:
ERROR_SUCCESS if the routine succeeds.
A Win32 error code otherwise.

ConnectivityVector - A pointer to the connectivity vector to be included
in the report.
NetworkId - A pointer to a string that identifies the network with
which the interface is associated.
Return Value:
