#include "complaint that what people *should* be doing is extending AMD, \
or something such as that, to handle SMB as well as NFS, so that
you can see all the hosts and available shares by CDing to
"/net" or something such as that, as well as through a file

(Well, maybe having the file manager know about that stuff explicitly
has some advantages, as it lets it put up icons that indicate that
something is a file server or an exported/shared directory from the file
server. I have the impression there's a fancy plugin mechanism - or
maybe more than one such mechanism - in Windows for remote file systems,
for that purpose.)

Grumble. The underlying problem here appears to be that the SMB client
in lisa isn't assigning a different MID to the two requests it sends out
- the NetShareEnum request has the same TID, PID, UID, and MID as the
NetShareEnum2 request, and, currently, the SMB dissector assumes that
won't happen, so that, for any SMB response, you can find the matching
request by looking for the request, from the same conversation, with the
same MID.
The only way to fix this would probably be to, when dissecting a
TRANSACTION reply:
if there's a "struct smb_request_val" attached to the frame, use
that;
otherwise, look up in the hash table for the matching request's
"struct smb_request_val", and, if found, attach it to the frame,
and then *remove* it from the hash table, so that the *next*
request in that conversation using that MID will get a new
"struct smb_request_val".
