Hi everyone,

I really hope someone can help me with this... I have 2 computers on
a network, CPU-1 is a win2k server that is a domain controller; PCU-2
is an XP Pro SP2 pc that is part of a workgroup.

Once a day, I want to connect to the "Q" folder (network share) on
CPU-2 from CPU-1, and count the number of directories inside the "Q"
directory. Since CPU-2 is not part of the domain, CPU-1 will require a
username and password to be set up on CPU-2. So I created the user
named "bak" with a password "auto" on CPU-2. "bak" is a member of the
administrators group on CPU-2.

To automate the process, I wrote a PHP script:

exec("net use m: \\\\CPU-2\\count auto /user:CPU-2\\bak");
exec("dir m:\\recordings > folderlist.txt");
exec("net use m: /delete");

I made a PHP script to do this because I want to contents of
folderlist.txt to be displayed on a webpage. For 24 hours, this worked
well. FYI, when the PHP script runs, the tasklist shows CMD.EXE being
executed by IWAM_CPU-1, which is the Built-in account for Internet
Information Services to start out of process applications.

Today, when I loaded my webpage, it didn't work. Here is what I have
found on CPU-1:

When I open windows explorer, I see drive M: listed as "Network Drive
(M:)", there is no path listed. Also, there is a little red x on the
drive icon. When I double click on the drive, I get an error: "M: is
not accessible. Access Denied." When I right click on the icon, and
select Disconnect, I get the error: "The network connection could not
be found."

These two error messages contradict each other. So I opened up a DOS
window, ran the net use command, and saw this:

Status Local Remote Network
--------------------------------------------------------------------------------------------------
OK \\CPU-2\count Microsoft Windows
Network

The network drive has no letter!

So then I read everthing I could find on Google Groups, but nothing has
worked. Other things that I have tried:

Ran regedit on CPU-1 and removed all entries referring to drive M or
CPU-2

ran the command "net use m: \\CPU-2\count auto /user:CPU-2\bak" in a
DOS window on CPU-1, which gives me System error 85: The local device
name is already in use.

ran the command "net use m: /delete /yes" in a DOS window on CPU-1,
which gives me the error: The network connection could not be found.

unshared the "count" folder on CPU-2 and re-shared it

deleted and recreated the user "bak" on CPU-2 with the same password

deleted and recreated the user "bak" on CPU-2 with a different
password, and modified my PHP script accordingly

created a new user with a new password on CPU-2, and modified my PHP
script accordingly


I'm stuck. The only thing I have not done is reboot either of the PCs,
because they run critical apps on my network. I'm at my wit's end. What
I don't understand is that everything worked fine for a day!
Any ideas, any suggestions, please!

You may need to restart to end the confusion, but before you do;

net use /persistent:no
net use * /delete /y

I do similar things and as a sanity check my first line is "net use /d
m:"
Normally this will fail as there is no drive M: connection but it will
be
handy should there be a connection leftover from the previous time
the script was run.

You might need to add "net use /d \\CPU-2\count" too which will
get rid of the connection with no drive letter.

Wow, that got rid of the listing in the output of the Net Use command.
Thanks.

Now, if I can just get rid of it in Windows explorer....

You must have a folder shortcut in your "Network Neighborhood."
The easiest way to get rid of these is from Windows Explorer.
* Go "My Network Places"
* Right click on "count on CPU2", select Properties, and verify
that the type is "Folder Shortcut." Hit [Ok] or [Cancel].
* Right click on "count on CPU2" again, select Delete, and confirm
it.
* This is also a good time to get rid of things like "My Web Sites
on MSN" if you are not using them.
* Start up a command prompt and type "Net use" - I suspect
\\CPU2\count will be back and so delete that using
"net use /d \\CPU2\count"

If you look in \Documents and Settings\LoginName\NetHood from a
Command Prompt you'll see a sub-folder named "count on CPU2"
which contains a single file, target.lnk. I'm not sure how/when
these get created but it happens automatically.

Marc,

I really appreciate the help. Sadly, there is no mention of drive M or
CPU2 in My Network Places, nor is there a folder in Nethood that refers
to CPU2 (or drive M). Any other suggestions?

Where and what exactly is the "it" you are trying to get rid of?
Earlier I had explained how to get rid of connections from the "My
Network Places \ Network Neighborhood" section of the folder list in
Windows Explorer. Those tend to show up with no drive letter when you
do "net use" from a command prompt. What shows up now when you do
"Net use" from the command prompt?

Marc,

Sorry about the confusion... As it stands tight now, when I open My
Computer, I see Drive M: (no path listed), and a little red x on the
drive icon. However, this entry does NOT appear in My Network Places \
Network Neighborhood.

In a command prompt, when I run net use, I see a listing:

Status Local Remote Network
--------------------------------------------------------------------------------------------------

Disconnected \\CPU-2\count Microsoft Windows
Network

I can remove this listing with the "net use /d \\CPU-2\count"
command, however, Drive M: still appears under My Computer.

it removes the entry from the list prodiced with the net use command,
but M: still shows in My Computer.

Thanks for the help guys, much appreciated. I'm going to stay up late
and just reboot the server around 1 AM.
