Parser Error Message: Access is denied

[kmyyf]

在部署调试一个ASP.NET站点，登录页面提交后总是提示如下错误：Parser Error Message: Access is denied.
查看了报错页面源码，里面内容如下：
[ConfigurationErrorsException]: Access is denied.

在网上查找了各种解决方案，一种说是由于Index Service引起的，但我一直都禁用着Index Service；另一种说法是由于目录访问权限引起，我将整个Temporary ASP.NET Files 目录的完全访问权限赋予了everyone,依然不行，请问还可能有其它原因吗

重新装一下你的framework 2.0 可能会有用

提示很明显，是Membership部分的权限问题...查查你用了哪种Membership Provider，如果是数据库有没有配置正确等等...
