Answer 1

According to your error above, you have IIS authentication configured on your Windows 2003 machine to allow two different types of authentication (integrated & anonymous). Change it to one type of authentication - the one that matches your WCF configuration. I'm guessing you only want anonymous (and not integrated) enabled in the IIS configuration, but that's your design choice..
