it is just the client checking if the file has any
AlternateDataStreams attached to it.

152.62.34.59 is client IP, 10.32.33.99 is a cifs server.
My question is I dont have any such special file or directory under
\rexhuang\, why the client send out such CreateAndX request?
Any input will be appreciated.
