HI, I just installed Exchange server 2013 Standar SP1 on a windows server 2012. I have 3 servers one is a Domain Controller, the other one has the MBX role, and the last one the CAS role, first i installed the MBX and after the CAS role, i passed prerequisite check without any issue. However when I tried access Exchange Admin Centre (ECP) at https:\\servername\ecp I got HTTP 500 Internal Server Error saying "This website cannot display the page. Most likely causes: 1. The website is under maintenance. 2. The website has a programming error." I tried access ECP at https://localhost/ecp and I got the same problem. Under either cases I was able to see the logon page of ECP and I was able to enter my credential (e.g. domain\user name, password). However I got HTTP 500 Internal Server Error at the next page.
I appreciate your help, on my case.
