I have a much bigger swork site I am trying to get working involving a chat system, but I am just doing this small example becuae I cannot get the ajax to work correctly.  I keep getting the error "asp .net ajax client-side framework failed toad"  and "Sys is undefined"  I have been googling this and most things point to the web.config file, but I still cannot get it working.  I also just repaired my ASP 3.5 sp1.

Try adding the controls into the web.connfig, eg:

<pages>
      <controls>
        <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<add tagPrefix="ajaxToolkit" namespace="AjaxNamespace" assembly="AjaxAssemblyName"/>
      </controls>
    </pages>

Alternatively add a reference within your control/page using a directive - just to pinpoint where the issue liies:
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>

Also check the versioning and the GAC (ie that any previous versions werent GAC'd or that strong naming might be required.

What generated your web.config? The  element belongs under  not  under . I also don't see an , which is needed for the script module. The following is one from one of my Ajax-enabled projects. It's 3.5, not 3.5 SP1, but it should still work.
