You are trying to utilize AJAX version 1. We do not have AJAX version 1 installed on the servers GAC only AJAX version 3.5. You will either need to update your code to utilize AJAX version 3.5 or upload the AJAX version 1 assembly in your applications bin folder. http://support.Winhost.com/KB/a693/microsoft-aspnet-ajax-information.aspx http://support.Winhost.com/KB/a817/could-not-load-file-assembly-systemwebextensions.aspx
