NTFS Access Control Lists and Inherited Permissions

When you deploy simple changes to your ASP.NET web application / XML web service (like copying in a new web.config file) watch out for cut-and-paste versus copy-and-paste! As it turns out, copying the web.config file will allow inheritable permissions to be applied to the new object - cutting and pasting the web.config will not. If IIS_WPG loses permissions to read the web.config file you'll see the error message: "Server Application Unavailable."
