SharePoint Designer 2010 Doesn't Work

Question

I can't open my site with SharePoint Designer 2010.

I get the well known message:

The Web server at "http://tfs" does not appear to have Microsoft SharePoint Foundation installed.

I've spent a good deal of time researching and troubleshooting already and have checked the following:

• Enable Client Integration is set to Yes for the web application
• All checkboxes are checked under the site collection's SharePoint Designer Settings
• Connecting to the Central Administration website from SD works no problem
• I can browse the site in the SD Open Site window, but when I actually click open, I get the error
• Logged in and tried as the SharePoint service account, the domain admin account, my account which is an admin, and the site collection admin account
• Creating a new site collection in the same web application and trying to connect to it yields the same error
• Compared all the site settings in IIS Manager between the Central Admin site and the web application running on port 80

How can I get this basic SharePoint functionality working (not that anything in SharePoint is basic from an administrative sense...)?

There is a KB Article available on Microsoft's site. It looks like you have not completed all steps in resolution that it suggests.
