remoting的Client如果访问IIS宿主server端要通过Firewall怎么办?

来源：互联网发布：淘宝上下架软件编辑：程序博客网时间：2024/04/24 05:18

问题描述：remoting的server是ＩＩＳ作host，Client环境访问internet要通过firewall，所以报

The remote server returned an error: (407) Proxy Authenticaztion Required的错误.

原因：访问远程站点的时候,用了代理,没有设置用户名/密码.

解决：你可以显示的拒绝用代理,或者制定访问用代理的用户名和密码.

   如果你的程序需要设置代理，比如remoting host在internet外面。请设置一个代理
