将本机上的网站(应用了ASP.NET AJAX 1.0)移植到服务器上(服务器上是windows 2000 server 操作系统，里面只安装了Framework2.0 和 SQL SERVER 2000，并没有安装 ASP.NET 2.0 和 ASP.NET AJAX 1.0)，运行时出现如下错误提示，如何解决啊？谢谢!
错误在第37行的： <add assembly= "System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 "/>
，说“系统找不到指定的文件”……
