So, I solved my first problem (needed to add my server to trusted sites in IE), but now when I try to run the "Small Business Network Configuration Wizard," I get the following error message:
The list of users and computers cannot be found. Before you continue, ensure that the client comptuer has a wired network connection. Also, if you have a router performing DHCP services on your network, verify that the router is configured to use the computer running Windows SBS as the primary DNS server.
I have made sure that I am both on a hard wire, and have manually set my server as my primary DNS to make sure that's not the issue.
