最近新开通的腾讯云服务器安装了IIS和FTP服务后，创建FTP站点使用FlashFxp连接不上。网上看了很多办法都不行。提示“列表错误; PASV 模式失败, 尝试 PORT  模式”,切换到被动模式创建文件夹可以成功，但是就是看不到文件也不能上传文件，折腾了2天终于在国外的论坛上看到几个相关词，研究了下终于解决了。如果尝试了以下方法都能解决，那就就用我的方法试试：

1、检查防火墙，是否允许20、21、22端口等；

2、重建FTP站点，检查读、写权限，检查站点文件夹权限，修改FTP密码等；

3、尝试关闭、打开FlashFxp的被动模式PASV 、主动模式PORT（我折腾一个通宵）等；

4、关闭、更换FTP软件，重启电脑、换电脑、重启服务器等；

5、看了网上几百条解决办法，咨询各种高手等；

6、检查服务器日志、重装FTP服务等。
        注意：以上方法均没有解决问题。

解决办法：

-------------------------------------

进入控制面板-硬件-设备和打印机，删除“Microsoft XPS Document Writer”这个虚拟打印机就可以了。
