When I use IE 8, it works porperly, I get a popup window asking for the password for ServerUser, but I am afraid my enduser has IE 7, and I he does not get the pop up window, just a "connection refused" error from html because it tries to open the application without asking for the server credentials.
I already checked on IE options: popup blocker, security tab and advanced options tab comparing their options and I do not find what could cause this issue;
