.NET interoperability

Hello, I'm trying to use ms .net as a client for a web service created using PEAR::Soap, but it seems the server response differs from the service created by a web service server created with .net, so the .net client doesn't seem to recognize the structures returned by the server. I created the php server using $server = new SOAP_Server(array('use' => 'literal', 'style' => 'document')); Can you give me any advices please ? If you need more details, just ask... Btw, if I try to use the PECL extension, php segfauls (bug reported to the sf.net project page). I use a wsdl file, created with .net, using the same object structure and methods... Thanks.
