Hello

I have Deployed a Exchange 2013 solution.

EX01: MBX+CAS

EX01 is a Server 2012 Standard with Exchange 2013 on it.

the Domain Controller is 2008 R2 Standard

I have done this installation a couple of times and never got this Error. really Strange, looked at a couple of the Services and they are stoped a couple of them, I can't even start them. I get a Error Massage.

the function level of the forrest is 2003 and all the prereqs went good. no problems during the installation. 

but after I restarted the Exchange server I couldn't log on to the OWA then after that I couldn't even go to the OWA page.

Error Massage:

Server Error in '/ecp' Application.
