Launching Flash in the browser from the command line

I am writing behavior test Flash using external interface in Flash, JavaScript in website and Selenium WebDriver in my program. All test is runing on Windows Server 2008 R2 within Internet Explorer 9. Everything works fine when remote desktop is connected to server (turned on). But when remote desktop is disabled, Flash doesn't work in browser. Program executes fine, browser is spawned, but JavaScript does not get response from Flash. I am running test on server from Jenkins using command line. How to resolve this problem? Maybe cheat Windows or Flash telling it, that remote desktop is connected? But how?
