Here's a great opportunity to get some free training - the Microsoft ASP.NET 2.0 Web Development Learning Series, where you can choose from over 80 learning modules – including 6 virtual labs, 28 on-demand sessions and 47 live webcasts.  These modules will be on a variety of web-related topics like ASP.NET, ASP.NET AJAX and Expression. Although the series is targeted at CFML, JSP and PHP developers, it’s a valuable resource for anyone interested in web development (including ASP developers) looking to learn more about the Microsoft web development platform. 

As a bonus, if you attend two webcasts and/or virtual labs, you'll get some great resources to extend your learning including some ebook sample chapters and a seat in an elearning clinic/workshop created specifically for PHP devs.
