It also can be used without running a scan, as general troubleshooting and best practice information to help you configure your server appropriately. If you have troubleshooting steps or information that would improve this article, please add it. For instructions on how to edit a TechNet Wiki article, see Wiki: How to Use the Editor.

Note: The following sections provide details about the specific issue. Italics indicates UI text that appears in the Best Practices Analyzer tool for the specific issue.
