[求助]求助：重新安装CAS时报错：Exchange server was not found [复制链接]

之前将Hub、CAS、Mailbox全部安装在一台Windows 2003上（FQDN：EXCHANGE2K7.sample.com），为了模拟真实环境，将这台Windows 2003删除上的角色全部删除，然后重新安装。
删除后在3台Windows 2003上分别安装Hub、CAS、Mailbox。AD使用原来的，邮件域也不变假如为sample.com。
安装Hub和Mailbox均正常，但安装CAS时出现错误，如下：
Exchange server "EXCHANGE2K7DEL:42a8fc5e-0de4-427e-afb0-5ba9d17dce3a" was not found. Please make sure you have typed it correctly.

setuplog中记录如下：

我在想是不是域控中某个地方记录了原来的Mailbox Server信息，该如何清楚呢？还是其他的原因，请教各位大侠，谢谢！

没人理我，也不知道如何排错，没有时间了。只有把AD卸载了重新安装，然后把所有的exchange role重新安装搞掂。
但还是希望有高人指点，如何在不重新安装AD的前提下解决这个问题。谢谢！

这个是DC的错误，我会拿DCDIAG来做下诊断。

哎，可惜论坛人手不够。不好意思啊楼主

多谢zanylee大侠的回复。
由于对DC不熟，能不能介绍一下DCDIAG针对此例该如何诊断呢？

论坛活到现在有一半都是因为 zanylee 。 zanylee 辛苦了。！

注意到这个object: EXCHANGE2K7 DEL:42a8fc5e-0de4-427e-afb0-5ba9d17dce3a"， 可能是由于安装过程中查找Default OAB服务器时由于该服务器已经被删掉了故造成该错

建议解决方案：

打开ADSIEDIT，展开至Configuration->services->microsoft exchange->org name->address list container->offline address lists，在右边打开Default Offline Address List的属性，找到offllineABServer，里面可能存在着已被删除的服务器DN(distinguishedName)，选择Clear清除之。将Mailbox服务器的DN复制在这里。

确定完成后，重新尝试setup。Good Luck~

看起来非常有道理，可惜DC重新做过了，要是还有现场就好了。
我们的这个论坛还是不错的！
