Subject: Level 257 FindFirst rejected by some Windows servers even though NTLM

A user sent me a trace of FindFirst level 257 (0x101 ) failing to Windows CE with NT Status: STATUS_INVALID_LEVEL (0xc0000148)

even though dialect negotiated was NT LM 012 and that dialect is the only prereq listed in MS-SMB for the level (see page 64).

How can the client determine under what condition that the server does not support that level - -  and what level to fall back (or move up to
higher level)?   Level 257 is pretty basic.
