active-directory – Exchange 2013安装程序失败 – 找不到企业

添加了新的Windows 2012 R2 DC,并迁移了必要的角色. 2003年的系统尚未降级,因此Forest / Domain功能级别仍然是2003年.

我的问题是Exchange 2013安装程序进程失败：

Setup encountered a problem while validating the state of Active
Directory: Couldn’t find the Enterprise Organization container.

错误链接到与情况不太相关的Microsoft article.此环境从未拥有Exchange服务器,因此以前的安装/尝试中不会留下任何工件.

看看ADSIEdit证实了这一点.

完整的安装日志条目如下：

07003 Failed [Rule:AdInitErrorRule]
[Message:Setup encountered a problem while validating the state of
Active Directory: Couldn’t find the Enterprise Organization container.
See the Exchange setup log for more information on this error.]

07003 [REQUIRED] Setup encountered a problem
while validating the state of Active Directory: Couldn’t find the
Enterprise Organization container. See the Exchange setup log for
more information on this error.

DC复制看似健康,DNS和AD站点和服务配置正确.通常的Exchange安装程序开关都不起作用(/ prepareSchema,/ prepareAD).一切都失败了同样的错误.

有关如何进行的任何想法？
