服务器重装后网站后台出现错误

       晕死。我也碰到这个现象了。源码

       没办法解决,源码好像是源码与服务器上的权限有关。

       开始以为是源码dll key 的原因。我都把Castle.net for 2.0的源码源码都重新编译了。还是源码出现这个问题。

        解决方法:

       给C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\DSS\MachineKeys文件夹Everyon用户加上"写"权限。源码exe源码破解工具这样就可以解决了。源码

        但服务器管理员不允许加“写”权限,源码无极源码伦理网怕系统安全问题。我晕~~~~~~~~
