ASP.NET AJAX client-side framework not loaded

I have basic default.aspx page as follows below, has ScriptManager tag
in it. And its associated cs code file nothing in it.
It runs without errors on the Developer's machine where VS2008
installed.

On our Windows 2003 Server, .NET Framework version 3.5 is enough to
run AJAX ( to use ScriptManager??)
Is anything else is required?
because we were running into the following error(s)

'Sys' is undefined (ASP.NET AJAX client-side framework not loaded).
On the Server IIS logs show that both WebResource.axd and
ScriptResource.axd came back with http-404.



<%@ Page Language="C#" AutoEventWireup="true"

I think you need some lines in the web.config, to get the
WebResource.axd recognized:

at least these lines in a <httpHandlers> section

<add path="*.asmx" verb="*"

When I look at the Server GAC

Two entries for both System.Web.Extensions and
System.Web.Extensions.Design


System.Web.Extensions 3.5.0.0 31bf3856ad364e35
System.Web.Extensions 1.0.61025.0 31bf3856ad364e35


System.Web.Extensions.Design 3.5.0.0
31bf3856ad364e35
System.Web.Extensions.Design 1.0.61025.0
31bf3856ad364e35


I tried to uninstall the version 1.0.61025.0, it says Assembly
'System.Web.Extensions' could not be uninstalled because it is
required by other applications.

Any ideas, again thanks in advance.

by uninstalling AJAX 2 Extensions 1.0.


I copied both
System.Web.Extensions.dll
System.Web.Extensions.Design.dll
From C:\Program Files\Reference Assemblies\Microsoft\Framework\v3.5 to
my project bin folder.


I restarted IIS, still having the same issue 'ASP.NET AJAX client-side
Framework Not loaded.
 
Finally I FIXED this issue, and frankly its very weird and very
simple.

I created the following two blank files (absolutely no content) in my
project root folder.

1. WebResource.axd
2. ScriptResource.axd

That worked on our Server, what a relief.
