Installing ASP.NET 2.0 AJAX Extensions 1.0 in Windows SharePoint Services Version 3.0
Windows SharePoint Services 3

You must install and configure Microsoft ASP.NET 2.0 AJAX Extensions 1.0 to work in a Windows SharePoint Services 3.0 environment. This topic describes the procedures to install and configure the ASP.NET AJAX 1.0 Extensions. The installation process deploys the ASP.NET AJAX 1.0 assembly (System.Web.Extensions.dll) to the Global Assembly Cache (GAC) and also installs the Microsoft AJAX Library JavaScript files. The configuration process tells Windows SharePoint Services 3.0 how to handle Web Parts that have ASP.NET AJAX functionality. It also registers the server controls as safe for use within Windows SharePoint Services 3.0.

Note that the procedure described below applies to .NET Framework 2.0. If you are using .NET Framework 3.5, change the version number in each of the XML code samples from Version=1.0.61025.0 to Version=3.5.0.0.

ImportantImportant:

You must complete these steps for each front-end Web server in the server farm.

To install Microsoft ASP.NET 2.0 AJAX Extensions

      name to the readAccessProperties and writeAccessProperties 
      attributes. -->

Found two missing commas

There are two missing commas in the code above. Make sure there's a comma "," between "Version=1.0.61025.0" and "Culture=neutral". You have to do this in two different places: <sectionGroup> and <controls> sections.

My entire sharepoint site was down because of this problem. I'm glad it was an easy fix.

Recommendation to adjust for 3.5.0.0 did not work
I haven't tracked down the problem yet, but simply replacing 1.0.61025.0 with 3.5.0.0 caused sharedpoint to stop working altogether with no useful information in the logs.
History
Version=3.5.0.0
You'll need to change the version numbers to Version=3.5.0.0 (From Version=1.0.61025.0) if you're targetting version 3.5 of the framework.

Missing , in article

There is a typo in this article:

<controls>
    <add tagPrefix="asp" namespace="System.Web.UI" 
    assembly="System.Web.Extensions, Version=1.0.61025.0, 
    Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
  </controls>

A "," belongs after "Version=1.0.61025.0".
