之前我一直用Dropbox管理文件，常用文件资料用Dropbox同步很是方便，免除了在办公室与家之间反复插拔U盘的繁琐，本来之前我一直用Dropbox管理文件，常用文件资料用Dropbox同步很是方便，免除了在办公室与家之间反复插拔U盘的繁琐，本来Dropbox都是开机后自动运行的，但最近Dropbox开机自启后无法建立连接。昨天开始Dropbox没有出现在开机启动之列，手动运行也不行，始终提示驱动器没有磁盘（见附图1-3），





   关闭该出错对话框又提示无法登陆Dropbox（见附图4）


今天百度到，Dropbox无法连接的解决方法，本想一试，无奈无法登陆。也顺便咨询下，网文说Dropbox无法连接是因为DNS被污染（个人认为可能是外国的东东被和谐了），可用DNScrypt解决DNS被篡改和污染造成的Dropbox无法连接问题，我下载安装了，由于Dropbox无法登陆，无法测试DNScrypt的威力。

系统是win8.1，期待有高手支招！谢谢！！
