Hi, Dochelp!

Attached find a trace that I could not explain according to [MS-SMB2]
or [MS-FSCC]. I open a file "y.txt" that does exist, see frame 33. I
create a directory "x", see frames 42/43. I then try to open
"x\..\y.txt" and get a STATUS_INVALID_PARAMETER in frame 55. I could
not find ".." to be illegal as part of a path in the docs.

Can you point me in the right direction?

The server is Windows 2012R2 in case that matters.
