Solution 1

There can be two problems
1. You are missing dll
2. Version can be a problem like if you are using 2.0 move to 3.5 or higher.

Have added the link for reference, as you need to check with IIS, .Net version and correct dll.

Solution 2

Many times the reference is not maintained when you move your root folder, so its better to keep the AjaxControlToolkit folder in the project. Then reference the dll file from that folder of the correct version, then you won't get such AjaxControlToolkit problem.
