You cant use decode as and select SMB since in wireshark SMB does not
run ontop of TCP and you van only DecodeAs in this regard for
protocols that run immediately ontop of the TCP layer.
In wireshark SMB runs ontop of NBSS which runs ontop of SMB.
(well, this si correct at least for SMB on port 139. SMB over 445
does not technically use NBSS but uses a different encapsulation
protocol that for all intents and purposes looks identical to NBSS,
which is why wireshark shows TCP->NBSS->SMB even for tcp port 445
even if it is technically not correct).
Thus: use DecodeAs and specify NBSS and it should work.
