ftp4j提示java.net.SocketException: Connection reset的解决
系统的自动更新FTP服务器，其他计算机连接都没有问题，包括xp、server2008、win7、win8，简体和繁体。

今天发现一台简体win7无法自动更新，提示错误如下：
java.net.SocketException: Connection reset

关闭win7自带防火墙，一切正常。

上百度查询，无果。
上google查询，答案见：http://stackoverflow.com/questions/10166337/ftp-error-while-downloading-uploading-with-ftp4j-library-in-java-application。

打开win7防火墙，以管理员身份运行cmd，运行如下命令：
netsh advfirewall set global StatefulFtp disable
问题解决。
