我有一个运行 Windows Server 2008 32 位版本的 AWS EC2 实例(中)。我想将它升级到 Windows Server 2008 R2。是否可以在不重新安装所有应用程序的情况下做到这一点?

今晚一些 IP 地址在邮件服务器的端口 25 上建立了近 2500 个连接。2500 是最大限制,50 个或更少的同时连接是正常的。一旦建立联系,他们什么也没做。IP 地址属于 Facebook 发送邮件服务器,但当然它们可能是伪造的。有没有人有过这样的经历?有什么好的方法可以防止它发生吗?

我有一个带有 IIS7 的新 Windows 2008 服务器。当我以活动模式连接到 ftp 时,它工作正常。在被动模式下,它会连接,但尝试获取目录列表时会超时。我尝试禁用两个防火墙,但没有帮助。我已经用不同的客户端机器和不同的 ftp 客户端软件尝试过这个,没有任何变化。有任何想法吗?
