<add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31b...

Facing issue when my team member try to upload compiled source code from her development machine to new production server.

Server Error in '/' Application.

Configuration Error

I've facing this issue before here. Anyway, here is how the problem can be solved.
  1. Copy AjaxControlToolkit.dll and AjaxControlToolkit.pdb version 1.0.61025.0 from my development machine to my ASP.NET App bin folder. (i install my AjaxControlToolkit in C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\AjaxControlToolkit)
  2. Copy System.Web.Extensions.dll (C:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions) and System.Web.Extensions.Design.dll (C:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions.Design) from my development machine to my ASP.NET App bin folder.

Or you can just comment that section out. This is what I did to move it to the production server.

I encountered the same thing after I migrated a development server. I am not a developer, so really had no clue as what could be the problem. But then after reading your suggestion, and then found that I had missed the installation of the .NET AJAX Extension 1.0. Once that is installed, the website shown another problem, which I would need to manually start the "ASP.NET State Service" (manually stopped by default). Now, it's working again. Thank you for your sharing and wondering solution!

Copying System.Web.Extensions.dll and System.Web.Extensions.Design.dll is enough, if you are not using any of the AjaxToolkit features.
