This script called ISAInfo.vbs will "dump" the configuration setings, rules, etc. from an ISA Server into a text file.
Easy way to "document" your ISA Server settings.

Note: To avoid accidental running of the script, the scripts on this web server are stored as *.vb_ file. Clicking on the link will bring up the script in the browser. From there you can save it for later use, simply by selecting All text in the browser window and copy/pasting it into your own newly created .vbs script file.
