Publish an InfoPath Form to a Website
A piece of a current project is to build an InfoPath form that will be published to a website rather than a SharePoint library. The developer on the project configured NTFS and the Web Application to post to the folder, and made sure Front Page Server Extensions (FPSE) were enabled. But, he still couldn't publish. I figured it was a WebDAV thing since this is now the "preferred" way to publish over HTTP and sure enough, this led to the solution. I found a great article on enabling WebDAV for IIS, now we're off.
Along the way I found a decent page from the InfoPath help which describes best practices for publishing forms. Thanks to the thinking-out-loud blog for writing something that turned up in a search.
