症状
请考虑以下情况:
-
证书服务 Web 注册角色服务安装在基于 Windows Server 2008 R2 的服务器上。
-
你有一台运行 Internet Explorer 10 或更高版本的客户端计算机。
-
尝试访问基于 Windows Server 2008 R2 的服务器上托管的证书服务 Web 注册页。
在这种情况下,Internet Explorer 中收到以下错误:
此 Web 浏览器不支持生成证书请求
原因
浏览器版本检查错误地将 Internet Explorer 版本标识为“IE 1”。
解决方法
此问题支持的解决方法如下:
-
在 Internet Explorer 中配置兼容性视图。
-
将 Web 注册页功能移动到Windows Server 2012。
-
修改 Certsbrt.inc 文件,方法是将第 44 行到第 70 行替换为以下内容。 Certsbrt.inc 位于以下文件夹中:
%WINDIR%\system32\certsrv\en-us
'' If there is no '.' in the UserAgent string, this will return the next character if any' as the version number. ' We extract the string until a '.' and then convert it' into integer.
