我有一台MS Exchange 2013服务器在我安装CU9 KB3087126之前工作正常。
的问题：
ECP无法从外部访问。
可以使用＆＃34; https://server_name/ecp＆＃34;从内部访问ECP;但在输入凭据后，我得到一个页面，其中包含＆＃34;服务器错误＆＃39; / ecp＆＃39;中的应用＆＃34;

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

在队列查看器中，我有很多电子邮件转向某些仍然存在错误的域名：
[{LRT=7/20/2016 2:40:17 PM};{LED=450 4.7.0 Proxy session setup failed on Frontend with '451 4.4.0 DNS query failed. The error was: DNS query failed with error ServerFailure'};{FQDN=correct_fqdn_here};{IP=correct_ip}]
什么有效：
OWA从内部和外部工作;
除了一些发送到特定域（小公司）的电子邮件，来自公司内部和外部的入站/出站电子邮件工作。（使用Gmail帐户测试，testconnectivity.microsoft.com并收到来自一些大公司的电子邮件的确认收到 - 前.hp.com）
除了CU9更新之外，在更新之前没有任何改变。
在询问之前搜索了很多网，但没有任何帮助。我猜大多数问题都是因为ECP无法正常工作。
之前有没有人遇到过这个问题，并且知道如何修复它？
提前致谢！
答案 0 :(得分：0)
经过大量研究后，我最终重建了IIS中的.net文件夹和AppPool实体。主要问题是IIS AppPools没有指向正确的ECP站点等。
现在它运作得很好。
