When we wrote Protect Your Windows Network we put some tools on the CD. The tools are now posted on the website: http://www.protectyourwindowsnetwork.com. There is even a new version of the passgen tool available there. The new version supports setting passwords up to 256 characters, which will make it impossible to log on with the account.
We also posted the errata for the book as well as updated our next few speaking engagements.
If you have any feedback on the tools, or anything else for that matter, let me know.
