Hi Volker,

Thank you for bringing this to our attention and providing a network trace. I will file a request to update our documentation as needed. 

It may be that this will go into [MS-FSCC].

Hello dochelp,

attached find a trace with an error code I can't find in [MS-SMB2] nor in [MS-FSA] in the places I would expect it.

Frame 17 sets bogus reparse point data on a fresh file, and frame 21 tries to delete that file again without the OPEN_REPARSE_POINT create option. It gets NTSTATUS code 0xc0000279, which Samba and Wireshark translate to IO_REPARSE_TAG_NOT_HANDLED. I would expect this error code to be mmentioned in

but I did not find it there.

Is it somewhere else defined?
