ECP / OWA 500 internal error message

Good Afternoon all;

We have just installed our first Exchange server (2013 SP1) on a 2012 r2 Standard server.

The installation went without any errors. I installed the mailbox and client access in one server. I followed technet 2013 help for installation (https://technet.microsoft.com/en-us/library/bb691354%28v=exchg.150%29.aspx).

After installation , I can open up the toolbox and the exchange powershell without any problems. 

However, when I try to access https://localhost/owa or ecp , I can put my username and password (domain\username and password) , it gives a 500 internal error.

I have tried the following

  • Resetting iis with iisreset (https://social.technet.microsoft.com/Forums/exchange/en-US/2f64d305-e9e2-4f48-a5b4-4f72d7bca801/exchange-2013-owaecp-http-500-internal-server-error?forum=exchangesvrclients)
  • Tried logging in with https://servername/ecp or owa (http://www.alihassanlive.com/e2k3/2014/2/9/cannot-open-eac-in-exchange-2013-500-internal-server-error.html)
  • I did this redirect thing, it did not help (http://msexchangeguru.com/2013/10/30/http-redirect-owa-ecp/)
  • Tried the netbios name (exchange) , it did not help, also tried netbios.domainname , it did not work either (http://community.spiceworks.com/topic/568178-http-500-internal-server-exchange-2013-ecp)
  • I CAN NOT FIND THIS SERVICE ON MY SERVER , if someone knows how to enable or find it, that might be my problem(

Make sure that the Microsoft Exchange Forms Based Authentication service is started. ??? Any ideas where I can find this service , I looked everywhere and did not see it.

  • I have not deleted the ECP or OWA directories from IIS yet.
  • I did do the authentication stuff (enabling windows authentication, forms etc.)

Any ideas WHY am I having the error message still ?

Note : We have a lab , and only 2 servers, one has the AD and the other one is only exchange server.

Thank you 

Note 2 : I have not done anything with AD after I installed exchange server (the user thats logging into exchange server is the administrator in the AD)

Hi Yigit,

Thank you for your question.

We could refer to the following steps for troubleshooting:

  1.        Change different browser to check if the issue persist
  2.        Make sure the difference in clock settings between the DC and the Exchange server is greater than five minutes. Try synchronizing the time between DC and Exchange server
  3.        Restart Exchange server and make sure Exchange ping DC without any problems(including DNS)
  4.        Turn off AD and Exchanges firewall  which is build-in to check if the issue persist

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim

Thanks for your answer Jim;

1 - I did use Google Chrome, If I do, It does not even show up the login page.

2 - I know that the time is SAME (not a five minutes difference) , I will do that today.

3 - Ping works on after restarting the server including DNS

4 - The firewalls are off on both end.

Any idea where Microsoft Exchange Forms Based Authentication service might be located ?

Any other ideas ?

Thank you

Just an input;

The clock change (on exchange server, its 7 minutes ahead), did not make a difference. 

I did read about some things might need to be changed on DC after re installing exchange server, Any on that ?

Thank you
