I/O Operation to a DFS Root Target or DFS Link Target Succeeds

When the operation issued to a DFS root target or DFS link target returns an NTSTATUS value with the Sev field set to 0 or 1, as specified in [MS-ERREF] section 2.3, the DFS client MUST complete the user/application-initiated I/O operation with the NTSTATUS value that was returned to the client.
