I often encounter "IELaunchURL() returned HRESULT 80070057" at the beginning of my test
script running.
It occurs at
WebDriver driver = new RemoteWebDriver(new URL("http://127.0.0.1:4444/wd/hub"), ie);
The IEDriverServer.exe launches sucessfully(I can see it in the task manager), and
I only can see the page "This is the initial start page for the WebDriver server."

What steps will reproduce the problem?
1.just start testing

What is the expected output? What do you see instead?
org.openqa.selenium.WebDriverException: Unexpected error launching Internet Expl
orer. IELaunchURL() returned HRESULT 80070057 ('E_INVALIDARG') for URL 'http://l

I also tried using
File f = new File("D:\\selenium-2.39.0\\IEDriverServer.exe");
System.setProperty("webdriver.ie.driver", f.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver(5555);
but the situation is the same.

This problem does not occur every time.

I've tried to search the solution, but I find this problem is really rare, so I guess
perhaps it's my environment's problem. I'm trying to use some other's computer to run
selenium2 and my test script. But I still want to ask does anyone know what will be
the probable reason, or how can I debug this issue deeper? Thanks a lot.
