I install .NET 4.0 on the server & their is bin folder & that also contain ajaxcontroltoolkit.dll in that. I am not able to find Application Pools in IIS of server I think default pool is .NET 2.0 so it's not working So how can I change that default pool?

Please ensure .net4.0 is installed on server and AjaxControlTookit is present in the bin folder.
