Maybe its something to do with who the system is trying to run the
command under?
I remember someone having problems try run WinZip through the exec()
command and it was down to what the service was being run under.

Dear Comrades,
Can someone please explain why this is script is not working on my win2k
box with PHP 4.3.4?
<?php
$email="[EMAIL PROTECTED]";
list($alias, $domain) = split("@", $email);
$command = "nslookup -type=mx $domain";
exec ( $command, $result );
$i = 0;
while ( list ( $key, $value ) = each ( $result ) ) {
if ( strstr ( $value, "mail exchanger" ) ) { $nslookup[$i] = $value;
$i++; }
}
while ( list ( $key, $value ) = each ( $nslookup ) ) {
$temp = explode ( " ", $value );
$mx[$key][0] = $temp[3];
$mx[$key][1] = $temp[7];
$mx[$key][2] = gethostbyname ( $temp[7] );
}
array_multisort ( $mx );
print_r($mx);
print "<br><br>";
print $mx[0][1];
?>
The same script works fine in another win2k box running PHP version 5. Strange
is that if I add print $result; right after exec ( $command, $result );
nothing is printed. When the script runs on the machine that works it prints
Array obviously. So, my guess is that $command is never being executed.
BTW, PHP is not running on safe_mode and the nslookup command works fine
on both machines.
Any help would be very much appreciated.
Kind Regards,

I tested your script on my Apache server running PHP 5.0 on WinXPPro...
it gives these errors:
----
Warning: Variable passed to each() is not an array or object in
D:\webserver\www\ICStrategy_MySQL\tests\exec.php on line 17
Notice: Undefined variable: mx in
D:\webserver\www\ICStrategy_MySQL\tests\exec.php on line 24

Ok, after some messing around I fixed it:
Replace
$command = "nslookup -type=mx $domain";
with
$command = "nslookup $domain";

Make sure that PHP is running with safe_mode 'off' in the ini

Thank you all for your answers! What was causing my problem? IIS Lockdown
Tool. Locks things so much that executing system functions even with
administrator rights is impossible. Solution? Remove the tool and make the
suggested changes manually, leaving some changes behind.
