I have 2 virtual servers setup on the same server. It's running Server 2003 R2/IIS 6 and Sharepoint services. Both are Sharepoint sites and both were setup manually instead of using the default site during Sharepoint setup. I'm the Sharepoint administrator for both sites.
I can access one of them (the first one I setup) without having to enter a username or password, but when I try to load the second one I have to authenticate or I get a 401.2 error. Both are set to use Integrated Windows Authentication and we have a 2003 native AD domain.
