Hi Everyone!

 I wasn't sure where to post this, so 'getting started' seemed like the best place.

 I've been getting the error Sys is undefined while trying to a simple Asp.Net AJAX web app from a tutorial on MSDN. I have searched many forums this morning trying to sort this out, but they all seem to focus on .NET 1.0, 1.1 or 2.0.

 My set up is as follows:

Windows XP pro, IIS 5.1, VS2008 targetting .NET 3.5.

 When I created the website (via the Tutorial's instructions) I did choose 'Local IIS' and clicked 'Create new web application'. Obviously, running on IIS 5.1, the website is created under 'Default Web Site'.

 I would be very grateful if someone could assist me with this problem, otherwise this newbie to Asp.Net AJAX might not get much further!

Many thanks in advance!

 PS - the tutorial can be found here... Go to the complete details ...
