4、下面是禁止3721的方法: 卸载3721后,用记事本打开c:\windows\hosts(查找,说明为文件),加入以下字符(IP和域名之间用一个空格间隔开): 0.0.0.0 www.3721.com 0.0.0.0 cnsmin.3721.com 0.0.0.0 download.3721.com 保存的文件名为Hosts(注意不要加任何扩展名),Windows 98/Me的系统把该文件保存到Windows目录,Windows 2000/XP的系统把该文件保存到WINNT\system32\drivers\etc目录,如果已经有Hosts文件,直接替换就可以。然后打开浏览器观察结果,怎么样?再也看不到3721的对话框了吧? 附件附上Hosts: # Copyright (c) 1993-1999 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # 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 individual # lines or following the machine name denoted by a \'#\' symbol. # # For example: # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost 127.0.0.1 3721.com #3721网络实名 127.0.0.1 3721.net #3721网络实名 127.0.0.1 cnsmin.3721.com #3721网络实名 127.0.0.1 download.3721.com #3721网络实名 127.0.0.1 www.3721.com #3721网络实名 127.0.0.1 www.3721.net #3721网络实名 XP/2K将上述内容存为 C:\\WINDOWS\\system32\\drivers\\etc\\hosts
