基于微软CA服务器为cisco路由器颁发证书

 

上篇文章说到用IOS路由器建立CA为***颁发证书验证，这次我们说下用微软的CA服务器为路由做证书认证

前提：

1.CA上开启IIS服务

2.必须在win 2003 上安装Resource Kit Tools (PS：这工具在2003的安装光盘上是没有的，必须上微软官方网站下载.-----> http://www.microsoft.com/downloads/details.aspx?FamilyID=9D467A69-57FF-4AE7-96EE-B18C4790CFFD&displaylang=en )

3.路由器时间与CA AD同步
4.安装完Resource Kit Tools 后，运行Command Shell--->输入cepsetup
 

 

 

 

记着这个地址一会要用

看见已经建立

  a few minutes.
