The value of the VersionNumber field MUST be 0x0004 for DFS_REFERRAL_V4.

The ReferralEntryFlags field contains an additional flag that can be set as follows.

 T (TargetSetBoundary): This bit is set if the target corresponding to this referral entry is the first target of a target set. The first referral entry MUST have this bit set in a DFS version 4 referral response.

The other bits of the ReferralEntryFlags field MUST be set to 0 by the server and ignored upon receipt by the client.
