我把服务器的windows文件夹权限给改了．而且把权限继承下去了．改后，所有的asp.net＋access的网站都出现错误，而asp＋access的没有错误．错误代码为：Server Error in '/' Application.

文件夹里要ASPNET可写入权限
还有LOCAL SERVICE
还有NETWORK SERVIE
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files文件夹设置了权限．ASPNET／LOCAL SERVICE／NETWORK SERVIE／IUSR_CNAME（internet来宾帐户）/都给了可修改的权限．
