I want to be really clear about this problem because I've seen the
same question posted elsewhere with 50 answers that have nothing to do
with the question.

I am running a server that has a shared "users" folder. When a user
(on an XP Pro machine) logs into the share, the user is asked his/her
username and password. This is perfect. However, that username and
password are stored until the user logs out or restarts the PC. As I
have many users of that PC (it's in a classroom), I do NOT want the
username and password stored when the user closes the window into that
server share. The next user who wants to use that share should be able
to enter his/her username and password WITHOUT having to logout of the
PC or restart it.

On Mac clients, this is not a problem as there is a "disconnect"
button that accomplishes this instantly. How do I make Windows forget
the username and password as soon as the share window is closed?

Thanks.

The general answer is: Put the following commands into the logon script (or
type them manually):
net use /persistent:no
net use * /del /yes

Please note:
- Both commands are required just once but can be executed any number of
times.
- The settings are specific to each Windows logon account.

Where might I find this "logon script"?

Thanks.

The "net use /persistent:no" does not seem to work. I issued it from
the command line then logged into the network share. It asked me for
the username and password (which is good). I then closed the window
into that network share, went back into Network Places and double-
clicked on the network share again. It opened immediately without the
desired login dialog. So the connection does still seem to be
persistent.

Pegasus,

Okay; your two commands seem to be the basis of what I need to do but
it looks like it needs to be a batch file. I used Notepad, typed in
those two lines, and saved the file as "logoff.bat". Then, when I
double-clicked the file, you could see the Cmd window appear (and I
think there's a command to make this appearance not happen, IIRC) and
the next time someone tries to access that network share, the
connection dialog appears. So this works.

Is there a way to add in one more iine of code to initiate the login
again? What I mean by that is if some form of the "net use" command
would, in essence, double-click on that network share and bring up the
login dialog? I'll play with this but suggestions are welcomed.

Thanks.

There sure is. Here is your complete batch file:
@echo off
net use S: \\ServerName\ShareName

Remember - the other two commands are not required after you have run them
once.

Before I saw your reply, I came up with this:

@echo off
net use * /del /yes
net use /persistent:no
echo Just hit Enter key twice to cancel login.
set /p user=User name:
net use x: \\192.168.1.2\Users * "/user:%user%"

Are you saying that the first two "net use" commands in my batch file
aren't necessary after they've been run once? Is that "per
session" (from the time the machine starts up until it's turned off)?
Or are they not necessary ever again after they've been run once?
Wouldn't I have to use the "del" line after one user is finished with
the share and the next user wanted to log in? They both have the same
share but all users can get to that folder; it's the individual users'
folders that reside inside the share and I assume that is why I need
to unmount and then remount. It looks like if I don't procedurally
unmount the share, it remains shared until I use the batch file to
unmount it (them, if there are a number of mounts). Am I making sense
here?

Thanks.

When I said "just once" I mean "just once", full stop. But as I said, both
commands must be run at least once *for every user*.

Once persistency is turned off, existing share connections are deleted when
the user logs off from his Windows session. Why don't you give it a try to
see for yourself?

The commands
echo Just hit Enter key twice to cancel login.
set /p user=User name:
net use x: \\192.168.1.2\Users * "/user:%user%"

should probably be
echo Just hit the Enter key to cancel login.
set /p user=User name:
if "%User%"=="" goto :eof
net use x: \\192.168.1.2\Users * /user:"%user%"
Note the moved double quotes in the last line.

While it is permissible to use IP addresses for the "net use" command, I
prefer NetBIOS names. They rarely if ever change.

I'm using the IP because the server has a static IP so that's not an
issue.

You said "when the user logs off from his Windows session" and that's
the problem: You may be thinking I'm using AD and we're not. Once the
PC fires up and arrives at the Desktop, the user never logs off the
session until the end of the day so I believe I have to use the "del"
command (to remove any currently mounted volumes even though a window
into that volume is closed). I would think the "persistent:no" command
could be run only once (as you've suggested) but, as it has to run at
least once (but it's okay to run more than once), I'll keep it in the
batch file. If it's the first time logging into the the server for the
day, then the "persistent:no" command is necessary even if the "del"
command is not. Thereafter, the "del" command is necessary even if the
first one is not.

I think I'm good. Thanks for your help!

Yes, I think you've got it pretty well sorted out.
