I was following your tutorial on Search Engine SiteMap and discovered I don't have a SiteMap.aspx in my root directory. I'm running DNN 5.6.1. Any ideas on getting one created? Thanks in advance.

This turned out to be an alias naming error. My port alias should have started with www. but it didn't. DNN creates the sitemap URL from the port alias so it was incorrect. Fixed alias name and all is well.
