An operation on a socket could not be performed because the system lacked suffic

现在办公用的windows经常出现IM可以继续聊天，但是浏览器还有新的联网的东西不能连到网络，之前靠重启解决了几次，后来找公司IT，告知我host绑定有问题，就把我host都清空了，也果然正常了。昨晚突然需要vpn回去解决问题，结果又出现这个问题，还好这次遇到了错误提示了：

An operation on a socket could not be performed because the system lacked
sufficient buffer space or because a queue was full

真是喜上眉梢，终于知道大概的错误原因了。

找了下ms的文档发现一篇文章不错

Understanding the error “An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.”

同时也可以自己用些工具查下哪些进程开了很多网络连接

active ports 或者ms自家的Sysinternals Suite 都可以帮助检测这个问题。
