Here is the error we are getting? The application works fine on our local computers, what is causing this? Please, don't tell us we have to have our IT department install anything on the servers either.

I am about to answer my own post in record time!

I have the solution for you!

Get the following dlls from

C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025

AJAXExtensionsToolbox.dll

System.Web.Extensions.dll

System.Web.Extensions.Design.dll

Once you have done that make sure you have the following files in your bin.

They came with the new install of AJAX.

Also we have to make sure that in our web.config under assemblies the PublicKeyToken portion is all Caps!

Good

PublicKeyToken=31BF3856AD364E35

Bad

PublicKeyToken=31bf3856ad364e35

We did this and are up and running now on our production server!

If you can run in full trust, then you can copy the binaries to the /bin directory.

Otherwise, yes, you will need to have the IT department install on the servers. (This is very much preferred... it allows for things like security patches to get to you via Windows Update.)

Thank you so much! Your suggestion solved my problem.
