Mike:

I believe you are in a better position than I to tell
why XXCOPY fails to create the subdirectory.

Apparently from your description, XXCOPY tries to do so.
So, the answer is on your system which only your careful
observation of the situation can produce the answer.

A few simple test can reveal whether it is a permission
issue or not. Within the same DOS Box (after XXCOPY
fails to create a directory), run a simple command like:

mkdir \\Computer_name\share_name\backup\mysubdir

(using the exact directory name which failed by XXCOPY.)

There are a number of situations that could
result in failure of such a command.

One thing which is really puzzling to me is that
in Win2K it works fine and not in Win9X. In most
cases, the situation would be the other way around
since the NT family OS has tighter security control.

Another scenario is if the destination already has a
file (it could be a hidden/system file) with the
intended directory name, it will fail.

Or, there may be a funny character in the pathname
(which is not in the standard 8-bit character set).

Also, we receive many tech support requests where
we find the culprit in Norton Anti-Virus and NProtect,
etc. which defy the regular behavior of the system.
I don't know how much time we have wasted on Norton
stuff. In my view, Norton AntiVirus should be
selectively applied to incoming files but not to
be run at all times for all files. At least, when
one is testing a funny behavior, he should always
disable Norton stuff while debugging a strange case.

At any rate, I strongly suspect that you may fail
to create the directory using a direct "MKDIR" method.
Having said that, I do not rule out the possibility
that XXCOPY is at fault.

BTW, we *ALWAYS* want to know the version number of
XXCOPY and the full command line which results in
strange behavior regardless of what is the most
probably cause (we hate to ask questions to answer
a question). In an innocent-looking case which the
user describe as "simple", we may find a missing
trailing backslash in the source specifier that
causes a syntactic ambiguity (I have posted numerous
message on this subject but I estimate the majority
of XXCOPY users do not put a backslash after a
directory name in the source specifier).

It is pointless for me to give you an exhaustive
list of all possible scenarios on how a directory
creation may fail (but I did list a few possible
scenarios --- I would not be surprised if none of
the scenarios I suggested here cure the problem).

Based on your description, XXCOPY succeeds
in trying. Beyond that, it is some "external",
environmental issue whatever that may be. That is
all I can say.
