Description:
------------
I am unable to access a shared directory on another windows pc by executing the windows "dir \\remoteserver\sharedir" function in php.

I have tried this using exec(),system() etc.

When I type the command "dir \\remoteserver\sharedir" on the windows command line (cmd) it works fine. If I do a "dir \\ownserver\sharedir" of the shares of the pc that I am working on, I am able to view them. It seems that when php executes the command to read another pc's shares, there may be permission problems?

Reproduce code:
---------------
<?php
/* Please change server name and directory name to
relevant windows share */
$server_name="radio";
$server_name="radio";
$directory_name="photos";
$share="\\\\".$server_name."\\".$directory_name;

$cmd=array(
"net use ".$share,
"dir ".$share);

for ($x=0;$x < count($cmd);$x++) {

echo "Command: ".$cmd[$x]." <br>";
$result = `$cmd[$x]`;
echo "The result is: <br>".$result." <br>";

}

?>

Expected result:
----------------
Command: net use \\radio\photos
The result is:
Local name Remote name \\radio\photos Resource type Disk Status OK # Opens 0 # Connections 1 The command completed successfully.
Command: dir \\radio\photos
The result is: 
Volume in drive \\radio\photos is Spare Volume Serial Number is 4C41-9557 Directory of \\radio\photos 05/07/2007  06:13 PM    <DIR>          . 05/07/2007  06:13 PM    <DIR>          ..

etc . . . . .

Actual result:
--------------
Command: net use \\radio\photos
The result is:
Local name Remote name \\radio\photos Resource type Disk Status OK # Opens 0 # Connections 1 The command completed successfully.
Command: dir \\radio\photos
The result is:
