What steps can be taken to check and adjust the permissions for a PHP program accessing a DCOM server on IIS?

To check and adjust permissions for a PHP program accessing a DCOM server on IIS, you can modify the DCOM settings to allow the PHP process to access the server. This involves setting the appropriate permissions for the DCOM server and ensuring that the PHP process has the necessary privileges to communicate with it.

// Set the DCOM permissions for the server
$com = new COM('servername');

// Adjust the permissions for the PHP process
$wmi = new COM('winmgmts:{impersonationLevel=impersonate}//./root/cimv2');
$processes = $wmi->ExecQuery('SELECT * FROM Win32_Process WHERE Name="php.exe"');
foreach ($processes as $process) {
    $process->Terminate();
}
