I am trying to add a service reference to axapta 2009. All is working well, its a simple web method(external webservice) that gets executed on the server tier(necessary, otherwise clr interop error)

But I've ran into the following problems :

1. is it possible to close the proxy one way or another? Because this option is not available in the generated service object in AX (only the webmethods and a tostring).
2. at a certain moment, i ran into a service with faulted state. Normally, you create the service object again, but this didnt solve anything, until i restarted the AOS. Is this normal behaviour? Is the service object cached or something like that on server side?

Thx in advance.
