Hello,

I have an Exchange 2013 SP1 DAG with 2 Exchange Servers.
On one Exchange Server I am not able to open the ECP, (On the other one it is working fine), but owa works on both.
After inserting the credentials into the login page, a blank page appears.


When I am check then the logs I find this warning with eventid 1309.
I already tried to recreate the HealthDatabases and the ECP VirtualDirectory. 
Below the warning code in the eventviewer

Anybody has an idea how to solve this, as I am going crazy with this error? 
Thanks a lot for any suggestion,

Hello Sathish,

I tried and retried also this already, but there was no change.

Still the same blank screen after login, and the above pasted screenshot.

Thanks

Thomas

At this point you should be on CU8 or CU9. Update to CU9 and see if that continues to repro.
