Hi,

Recently we install Exchange Server 2013 CU7.

After rebooting the server, we cannot access the ECP. After login, give error 500.

OWA is working fine, as well as Exchange Power Shell.

Error 4 in Event Viewer > Application

"falhou com o seguinte erro:

Someone know what is the problem?

Sincerely,
Marcos Fernandes

The first thing to check,

Are all app pools in IIS Manager started?

Hi,

Yes they are. we have CAS and Mailbox on the same server. OWA is working ok for all user's and for Administrador to. I cant figured out what is the problem... Can you help me?

Sincerely,
MF

Hi,

Please check on the Application Pools to view whether ECP Application Pool is running on .NET Framework v4.0. It maybe the incompletely installation of Framework that causes this error.

If so, We can try to run the following command as Administrator:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

Or change the MSExchangeECPAppPool from .NET Framework from v4.0 to v2.0. Then restart IIS to have a try.

If this issue persists, please try to recreate ECP virtual directory to check this issue.

Recreate-ECP Virtual Directory:

Remove-EcpVirtualDirectory -Identity Servername\ecp (Default Web Site)

New-EcpVirtualDirectory -InternalUrl https://ServerFQDN/ecp -WebSiteName Default Web Site

Meanwhile, please look up into IIS log file to find any errors related to MSExchange on the Exchange 2013 Client Access Server, file path: c:\inetpub\logs\logfiles\W3SVC1.

Best Regards.
