I spent last night installing the latest version of AuthAnvil and RWW-Guard on our network. Between the two, we now have a far more secure environment that enforces Two Factor Authentication (TFA) for access to critical accounts and resources. Normal Windows authentication is a single factor authentication...
Finally, Microsoft has released an ISA Firewall Client that officially supports XP x64 and Vista. The download is a single download for both 64-bit and 32-bit, and is the same for all supported versions of Windows, up to and including Vista RTM. So go grab it here .
