This isn't an issue with PHP. The SetPriority method on the Win32_Process Method is only available on Windows XP and Windows 2003. Previous Comments: ------------------------------------------------------------------------ [2004-09-28 20:36:29] steve at qzed dot com 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.'
