Hello list members!
I joined this list on May 1st and I can see I have a lot to learn. Thanks
to everyone - especially those *@samba.org folks. You are so appreciated.
Background in my plea for help: I'm the IT guy for a family owned community
bank in Southern Colorado. I am very tired of the limitations and security
problems of Micro$oft and have committed to learning and using Linux (and
Samba) in hopes of replacing the Windows NT servers, and eventually some
workstations, we are currently using.
I am successfully using Samba on several servers running RedHat 7.2 with
various versions of Samba (2.2.1a, 2.2.3a, or 2.2.4). But there is one
piece of software which does not function right while hosted on a Samba
file share. It's software built specifically for banks and so it's not
built as well as a lot of software. Anyway, I'll do a database query with
this software (database is not on the Samba box) and the first one will
work. However, every time I click to query the database record further,
the software comes back with an error message that it can't find a needed
DLL file. As you will see below, it really isn't a DLL file missing . . .
Here is what I see in a packet capture from Ethereal when I initiate the
second query.
From client to server: NT Create AndX Request, Path:
\ITI\PREMIER\PRM1101.EXE\2
From server to client: NT Create AndX Response, Error: STATUS_NOT_A_DRIECTORY
Now, I don't know why the software adds the \2 at the end when you do the
second query, but somehow it doesn't bother the software while hosted on a
Windows box.
Here is what I see in a level 8 Samba log file at the same time:

NT_STATUS_NOT_A_DIRECTORY
So Samba thinks, and rightly so, that the \2 at the end is a directory
name. Only a virus like Microsoft Windows could understand
\ITI\PREMIER\PRM1101.EXE\2 as a file name with a \2 as some sort of command
line parameter.
I've tried so many things I can't remember them all. I've tried making a
link \ITI\PREMIER\PRM1101.EXE\2 pointing to \ITI\PREMIER\PRM1101.EXE. I
read a little about name mangling and tried to use a mangled map rule to
change *.exe\2 to *.exe or *.exe \2. I've been trying to figure out how I
might implement rewrite rules like you can in Apache or sendmail.
I would appreciate any help/ideas/work-arounds anyone could give me. This
problem is the only thing keeping me from removing all the Windows servers
from our branch offices!!!
Thanks in advance.
Mike
