If you are a network admin or security admin at your company, think you will find this really interesting, if not already known to you.
Microsoft Visio 2003 and 2007 versions have a connector for MBSA (Microsoft Baseline Security Analyzer) which can be downloaded from here:
If you have ever used Visio, you probably know that it is an effective tool for creating network diagrams. However, you aren't limited to creating these diagrams manually. You can create an MBSA-suitable diagram manually, but it's a lot easier to use LANsurveyor. You can use the LANsurveyor for Visio tool (it's in the Visio 2003 Resource Kit) to automatically create a Visio diagram of your network.
Once this diagram has been created, you can add in the Visio connector for the Microsoft Baseline Security Analyzer, and that allows you to initiate MBSA scans directly from Visio by clicking on computers that appear on the diagram. You can also import existing scan results. The diagram is then color coded to reflect the scan results. You can even view the MBSA report for each machine directly through Visio.
