新手求助，我是第一次用CMS，对asp和数据库不太懂。
我的系统是windows XP professional，装的是IIS5.1
我把默认网站的主目录改成下载的风讯源码所在目录。
以上是我所做的所有操作，没有其他操作。
登陆后台时，出现：

抱歉！操作失败

我还需要做哪些操作？
高手帮帮忙，指点一下，先谢过了！

正常情况下是不会出现这种问题的,你看看IIS的设置呢.

需要对数据库或是文件权限做一下设置吗？对数据库和文件权限不是太明白

一点心得： 1，要将风讯目录设为根目录。 2，将风讯目录取消只读权限。 3，IIS的设置。

是安装成功后登陆后台出现这样的错误的吗,重新解压安装文件,重新安装.

谢谢各位朋友，我终于登陆后台了

问题解决了就好!
