unable to login EAC and EMS

Hello everyone,

Am getting following error when i try to access the EMS, also the EAC is not even accepting the Admin credentials.  

We had an issue with the previous exchange 2013 installation and had  to manually reinstalled . Now the installation is OK and i can see all the services and Directories are working. But it doesn't allow me to login . I have checked the permissions , the admin has Enterprise admin, domain admin, organization group privileges.

Note: Both DC and exchange running on the same system

Operating system: windows server 2012 R2 standard

Exchange version : Exchange 2013 CU8

New-PSSession : [hoXXXXXXXXm] Connecting to remote server hoXXXXXXXX.com failed with
the following error message : Access is denied. For more information, see the about_Remote_Troubleshooting Help topic.

Are all of the Microsoft Exchange Services that are automatic started?

Try restarting the Microsoft Exchange Topology Service on the machine too.

Are there any relevant errors in the application log?

Access is denied. For more information
As stated already Access Denied is 99% a permission issue. The other 1% can be from a firewall related scenario.

Hi all,

Just realized "Windows server Essentials experience" is already installed as a role in the server. Could this be  a problem ?
