我将一台Windows 2008 R2服务器configuration为具有Active Directory域服务和DNS服务器的域控制器。
DNS服务器最近被卸载并重新安装，试图修复（可能不相关的）问题; 事件日志以前充斥着错误（＃4000，“DNS服务器无法打开活动目录…”）重新安装没有解决。 然而，在至less从本地networking上缓慢地显示和parsing名称之前， 现在它什么也没有显示出来。
（原始错误是以＃4015错误开始的 “DNS服务器遇到来自Active Directory的严重错误”，后跟一串长度为＃4000和几个＃4004的string，这可能是由于新的DNS名称为最近补充说，但我不能确定时间。）
尝试通过Administrative Tools > DNS会导致错误：
SERVER SERVERNAME无法联系。
错误是：
访问被拒绝。你还想添加吗？
select“是”只是将一个SERVERNAME项目放在列表中，但是所有的configuration选项都是灰显的。
我试图编辑我的主机文件按照这个职位，但无济于事。
运行dcdiag ，它可以正确识别主服务器，但立即失败，testing连接：
开始testing：连接
主机blahblahblahyaddayaddayadda无法parsing为IP地址。 检查DNS服务器，DHCP，服务器名称等
在检查LDAP和RPC连接时出错。 请检查您的防火墙设置。 ……………………. SERVERNAMEtesting连接失败
添加blahblahblahyaddayaddayadda地址主机（指向127.0.0.1），连接testing成功，但它似乎并没有解决的根本问题（访问被拒绝），所以我再次散列出来。
主DNS服务器根据ipconfig /all正确指向127.0.0.1。 并且DNS服务器正在将请求转发到外部地址（如果缓慢），但是parsing本地networking名称是被冻结的。
DNS数据库本身是足够小，我（勉强）能够重build，如果需要，但DNS服务器似乎并不愿意让我一起工作（或周围）。
（是的，在你问之前没有可用的系统备份）
我从哪里出发？
根据要求，我（稍微混淆）的dcdiag输出：

和我的hosts文件（为了简洁，减去散列的行）：
127.0.0.1 localhost ::1 localhost
而且，为了完成，这里是我的（5000行加） netstat -a -n输出的选定块：

你有没有尝试安装第二个DC与AD DS，DNSangular色？ 然后从旧DC抓住FSMO的angular色？
之后，您可以降级旧的DC，并在稍后推广。
