Another great tool to have handy - Security Readiness Kit. Here's what TechNet says about the tool:
“The Security Readiness Kit (SRK) CD and its companion web site at http://www.microsoft.com/technet/security/readiness are designed to give you easy access to the documentation and tools you need to ensure that your network operates with the best security possible.”
If you have TechNet, I believe you should have it in there (but don't quote me on that :-)). There is upcoming web page to order the CD as well.
