COM doesn't run

[Ilya]

I write an application that calls COM objects from PHP and I've used a small package Denwer for its debugging. Now came its deployment and it was installed a standard PHP package that integrates with IIS to run on a server. The standard PHP function executes successfuly but COM objects calling failes. Appers "'com_exception' with message 'Parameter 1: Type mismatch" in string
$objU = new COM ("Deans_Project.User");
Tell me please how to make working COM objects calls.

maybe better use like in manual?
<?php
$domainObject = new COM("WinNT://Domain");
while ($obj = $domainObject->Next()) {
echo $obj->Name . "<br />";
}
?>
