部署exchange提示“因为父类不在可能的上级列表，不能添加该对象”

    前几天部署exchange2013SP1的时候，在部署前端的时候，安装步骤执行的时候，忽然出现下面的错误：

出现这个问题，初步认为是架构准备的时候没准备完成形成的，卸载了已安装的exchange，而后ADSi删除，从新准备环境，部署依然报如上错误。

    经过查阅资料，发现是由于架构里面的每个值的属性值丢失形成的。对比个人测试环境，进行逐个排查，终于找到了一下问题

在ADSI--链接到架构--发现CN=ms-ex......的属性里面的posssuperiors值丢失，

参照个人测试环境的值，添加以后，保存

从新运行，安装经过，成功

出现这类问题，可进行如下值的排查：

In the list of attributes below, you will need to verify / add the possSuperiors objects by double clicking the CN=... object, scroll down to the Attribute possSuperiors, double click possSuperiors and add each item individually. I have separated them with a comma below but they will be individual items in the list box. If the objects in possSuperiors already exist, move on to the next item.  Also, please note that the added items must be typed exactly as they are shown below. 

1. CN=ms-Exch-Information-Store

     1a. possSuperiors = msExchExchangeServer

2. CN=ms-Exch-Exchange-Transport-Cfg-Container

      2a. possSuperiors= msExchExchangeServer

3. CN= ms-Exch-Exchange-Admin-Service

     3a. possSuperiors = msExchExchangeServer,computer,container

4. CN= ms-Exch-MTA

     4a. possSuperiors= msExchExchangeServer,computer,container

5. CN= ms-Exch-Protocol-Cfg-Shared-Server

     5a. possSuperiors = msExchExchangeServer,computer,container
