I am fairly new to the web site field and was trying to get a good sitemap generated. I installed as directed but am unsure if I have the file permissions set correctly on our Windows 2008 R2 server. When attempting to access [external links are visible to admins only] (modified for my domain of course) I get an Error 500.0 - Internal Server Error. There is a problem with the resource you are looking for, so it cannot be displayed. I assume this has to do with the permissions but have not been able to fix it. Suggestions?
