Loosely related question - how do the normal windows desktops clients determine how to fall back (or move up to newer) infolevels for
FindFirst.   We would normally use SMB_FIND_FILE_ID_FULL_DIR_INFO
(level 0x105 FindFirst) but we end up calling FindFirst level 0x101 (which does not request "uniqueids") since QueryPathInfo level 0x3EE
(QueryFileInternalInfo) gets NT Status: STATUS_INVALID_LEVEL
(0xc0000148) fails.
