我的域上有两个 GPO ->“默认域策略”和“ GPO - Diretoria ”。默认域策略配置为在客户端的所有 IE 浏览器上设置代理设置（用户配置 > 策略 > Windows 设置 > Internet Explorer 维护 > 连接 > 代理设置）。以下是使用的详细配置：
Internet Explorer Connection
----------------------------
HTTP Proxy Server: 192.168.100.1:3128
Secure Proxy Server: 192.168.100.1:3128
FTP Proxy Server: 192.168.100.1:3128
Gopher Proxy Server: 192.168.100.1:3128
Socks Proxy Server: 192.168.100.1:3128
Auto Config Enable: No
Enable Proxy: Yes
Use same Proxy: Yes
在另一个 GPO ( GPO-Diretoria ) 中未配置代理设置。“启用代理设置”复选框在“代理设置”窗口中被禁用。此 GPO 链接到名为Diretoria的 OU 。在这个 OU 内，有 3 台计算机。当我在 3 台计算机中的任何一台中执行 gpupdate（甚至是 gpupdate /force）时，代理设置仍然设置为默认域策略中的配置！
然后，我只使用用户配置设置执行了各种测试，并且我注意到（通过运行gpresult /z）在默认域策略 GPO 上设置的任何用户配置设置都不能被“GPO - Diretoria”用户配置设置替换！但是，计算机配置设置已被完美替换！
