It seems you are running IIS and QVWS in the same computer using the same port. Although in the latest versions of Windows this should not be a problem (port sharing in Windows or so) if this is not properly configured this can conflict with your Server. When you installed it, did you set it to use the QVWS or IIS? If the latter, did you follow the steps in the Server Reference Manual to grant permissions, set up .NET and so? You can change the port, and make sure there is no proxy configured in your browser, so you can get to the console right.
Hope that helps.
