This isn't an issue with PHP.

The SetPriority method on the Win32_Process Method is only available on
Windows XP and Windows 2003.

Description:
------------
I am using the COM object of PHP to access WMI.  
I can access Win32_Process objects and display their property values.
When I try to use Win32_Process method SetPriority I get a PHP error:
'Unable to lookup setpriority: Unknown name.'

Reproduce code:
---------------
<?php

   set_time_limit(0);

   $shell = new COM("WScript.Shell");

   $cmd = 'php.exe st1.php';
   $st1 = $shell->Exec($cmd);

   echo $cmd." Started as ProcessID ".$st1->ProcessID."\n";

   $wmi = new
COM('WinMgmts:{impersonationLevel=impersonate}!//./root/cimv2');

   $query = "Select * from Win32_Process where ProcessID =
".$st1->ProcessID;

   $stillRunning = true;
  
   while ($stillRunning) {

      $stillRunning = False;

      $processes = $wmi->ExecQuery($query);

      while ($process = $processes->Next()) {

         if ($process->ProcessID == $st1->ProcessID)  {
            echo "process ".$process->ProcessID." still running\n";
            echo "process ".$process->ProcessID." priority is
".$process->Priority."\n";

            $priority = 128;
            $process->SetPriority($priority); //high 

            $stillRunning = true;            
         }
      }

      sleep(2);
   }


   echo "process ".$st1->ProcessID." ended";

?>

Expected result:
----------------
D:\d2>php tm.php
Content-type: text/html
X-Powered-By: PHP/4.3.8

php.exe st1.php Started as ProcessID 1052
process 1052 still running
process 1052 priority is 8
process 1052 still running
process 1052 priority is 8
process 1052 still running
process 1052 priority is 8
^C

Actual result:
--------------
D:\d2>php tm.php
Content-type: text/html
X-Powered-By: PHP/4.3.8

php.exe st1.php Started as ProcessID 1488
process 1488 still running
process 1488 priority is 8
