你好，楼主，你先看看HOSTS文件有没有被修改。

C:\WINDOWS\system32\drivers\etc 应该是这个文件夹下的hosts 文件
直接用记事本把里面的内容删掉就行了我的hosts文件贴给你

# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.

# Additionally, comments (such as these) may be inserted on indivial
# lines or following the machine name denoted by a '#' symbol.
