According to [MS-SMB2] 18.104.22.168.7 (http://msdn.microsoft.com/en-us/library/cc246784%28v=PROT.13%29.aspx), smbd must reply with NT_STATUS_OBJECT_NAME_NOT_FOUND as it does not support durable file-handles yet.
I have seen w2k8r2 running xcopy /C ending up in an endless loop trying to get back the original file handle from us sending the same requests over and over.
