Description:
------------
When trying to call the com object winmgmt I get the following error.

Fatal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `winmgmts://./root/cimv2': ' in C:\Inetpub\wwwroot\sqladministrator\wmitest.php:4 Stack trace: #0 {main} thrown in C:\Inetpub\wwwroot\sqladministrator\wmitest.php on line 4


Reproduce code:
---------------
<?php
$hostname = ".";
//com_print_typeinfo ("winmgmts://./root/cimv2");
$wmi = new COM("winmgmts://./root/cimv2");


  $names = $wmi->ExecQuery("Select Name, Manufacturer, Model, NumberOfProcessors, TotalPhysicalMemory 
  from Win32_ComputerSystem");
  foreach ($names as $system)
  {
   echo trim($system->Name).'<br>Manufacturer: '.($system->Manufacturer).
    '<br> Model: '.($system->Model).'<br> Number of Processors:'.($system->NumberOfProcessors).
	'<br> Physical Memory: '.(($system->TotalPhysicalMemory/1024)/1024).' Mg';
  }
?>

Expected result:
----------------
The manufacturer, the number of procesors and amount of physical memory on the server that this is run on.

Actual result:
--------------
Fatal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `winmgmts://./root/cimv2': ' in C:\Inetpub\wwwroot\sqladministrator\wmitest.php:4 Stack trace: #0 {main} thrown in C:\Inetpub\wwwroot\sqladministrator\wmitest.php on line 4

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

winmgmts://./root/cimv2 is not a valid com object name so COM couldn't instantiate it, therefore it threw an exception.

You didn't catch the exception and all uncaught exceptions are fatal.

Check this out:

Someone recently reported to me that they needed to set the impersonation level, as shown towards the end of that page.
