我在浏览器地址栏输http://localhost后显示
The requested URL could not be retrieved
While trying to retrieve the URL: localhost/
The following error was encountered:
Unable to determine IP address from host name for localhost
This means that:
The cache was not able to resolve the hostname presented in the URL.
Check if the address is correct.
我打其它的虚拟站点地址也是这样，我重装了IIS，还是不行，怎么办啊？
我都没办法了，急啊

用“http://主机名/虚拟站点名” 这样浏览器可以看了。
但是在UD里cnn测试时还是报错如下：
HTTP error code 505 sersion not suepported
an unidentifed erroe has occurred
而且live data也报错

这些站点里的东西都是以前做的，上传后都是好的，我现在想改里面的东西，怎么办呢，我不想用手工改啊
