Many folks asked us at PASS last year for these labs. A little late coming but we have these available if you want to download these. I've got these posted on Ken Henderson's website at http://sqlnexus.net/download/pass_2006_Web.zip. There is no official support for these labs and please do not install these on a production server. They are intended for learning only and should only be put on a server where you won't alarm your organization when errors and problems appear (which is the point of the exercises).
