DNS记录重建
|
按照截图一步一步来。
1.从图1中可以看到，为了模拟故障，我已经把所有区域都删除了。 2.新建一正向查找区域：ris.com。具体域名自己更换。如图2 3 4 5 6 同样的方法，再新建一正向查找区域:_msdcs.ris.com.我就不截图了。 3.运行 nltest /dsregdns命令强制重新注册所有DNS资源记录，包括特殊的DNS资源记录，例如SRV记录， 这个工具需要安装系统安装光盘上的support tools才有。 4.再重启net logon服务和DNS Server服务。
5.回到DNS服务管理器，发现所有的区域资源记录都回来了
6.在客户端利用nslookup进行测试。
