proliferation of SAMBA links in W2K

[Ana Esparza Keys]

Hi!
I'm pretty new to using Samba and have come accross a puzzling problem that
I cannot figure out with the documentation or Samba books... please forgive
me if this has been discussed before in this forum, I have not seen such
discussion.
We have a customer that uses a script that basically  maps to three samba
shares, then uses the substitute command repeatedly.  Every time a subst
command is issued, a new Samba link is created instead of using an existing
link.  As a result this customer may end up with 20 or more links (more
links are also created when using the command dir, for example) and his
workstation freezes.  This only happens from a Windows 2000 workstation and
so far only when running this script.  The version of Samba we are running
is 2.0.7 ... has ANYONE seen this problem before??  Please help if
possible.  I'm including the customer's script and our smb.conf file.
Please let me know if there is other information I should include...
-- Thank you very much!

Anabel

Configuration file (smb.conf)

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not many any basic syntactic errors.
