The Europeans have put up a couple more presentations from IT Forum 2005. There is a tape of my Is That Application Really Safe demos, as well as the Security Policy Management with SCW. They also put up Jason Zions' Unix/Linux Authentication with Active Directory presentation.
For a complete list of taped presentations available online check out the listening room at the Protect Your Windows Network site.
What a pity that they can't be downloaded - I'd love to watch half this stuff on the bus, and my bus route doesn't (yet) have wireless.
Every so many stops, I can get enough network access through somebody's home wireless... but it just isn't reliable enough for streaming :-)
