there is a server with Exchange 2013 CU2 installed. i logon on this server via RDP session with domain administrator credentials. this domain admin account is also a member of "Enterprise Management" group. right after installation ECP was accessible via browser without any trouble but OWA wasn't working at all. i've started to turn on and off various authentication options via IIS Manager and as a result none of the Exchange 2013 Web Apps are working properly.

Exchange Powershell won't connect with an error "Access is denied". OWA and ECP showing login page but won't go further. If credentials are right then those apps just reload login page without any errors. If credentials are wrong, login page show standard error message about incorrect user or password.

IIS Server Authentication currently set to Anonymous with IUSR as user identity. Default Website Authentication is set to Anonymous with IUSR as user identity. EPC Virtual App Authentication is set to Anonymous (with IUSR) and Basic (with no default domain or realm). OWA Virtual App Authentication is set to Windows with Extended Protection set to Required and Kernel-mode is turned off. Powershell Virtual App Authentication is set to nothing right now.

What authentication on what level shoud i turn on to set this right?

Hi,

Please try to reset the CAS virtual directories.

After doing this, the old virtual directory would be removed and a new virtual directory with default settings can be created, including default Authentication Settings.

There are some references about it below:

If the issue persist, please collect the error logs in Event Viewer. You can post it here and I would like to help you.

Thanks,

Winnie

trouble is - there is no EMC in my Exchange 2013 installation. i've got only Exchange Administrative Center shortcut, Exchange Management Shell shortcut and Exchange Toolbox shortcut - no EMC there.

Hi,

In Exchange 2013, there is no EMC (Exchange Management Console) but EAC (Exchange Administration Center) there.

The EAC replaces the Exchange Management Console (EMC) and the Exchange Control Panel (ECP), which were the two interfaces that were used to manage Exchange Server 2010.

For more information, please refer to the article below:

thanks,
