ICS Internet网络共享 整个流程设置

netsh winsock reset netsh int ip reset ipconfig /release ipconfig /renew ipconfig /flushdns


这些命令会重置网络套接字、重置 IP 协议、释放和更新 IP 地址、清除 DNS 缓存，从而恢复网络的正常工作。

方法1：(二娃亲测有效)

1、选中“Internet Connection Sharing”这个服务右键，点击属性打开，启动类型选择“自动”，确定保存

2、找到路径：HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\SharedAccess下，添加一个注册表子项
3、在空白处右击鼠标，新建“DWORD（32位）值（D）”，名称叫做“EnableRebootPersistConnection”，将数值数据改为1。

方法2：（未测试）

查了下资料，可以通过INetSharingManager来实现，原理很简单： 模拟手工的动作自动化操作。
