I completely missed this one; the SharePoint Diagnostics Tool was recently released (included in the Microsoft SharePoint Administration Toolkit v3.0).  The SharePoint Diagnostics Tool enables an administrator to simplify troubleshooting by gathering pertinent information about a farm and displaying it in a meaningful way providing a programmatic approach to locating and isolating issues in your environment.  Find it and other great tools and utilities under Tools.
