Hello!

Yesterday I installed CU3 on my test Exchange 2013 server (in the VM), - the installation completed successfully. I tested ECP and Outlook - everything worked out well.

I then shut down the server and started it today afternoon. Here is the error I have been presented with after running ECP:

Tell me please what can be the cause of this? The server is not operational now...

Thank you in advance,

Hi

Are all your services started? WWW services started with all dependencies?

Yes, there are no errors in any Windows logs, all services are started. IIS is up and running.

Hello,

Please try to recreate ecp virtual directory to check the result.

If the issue persists, please try the following method:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files, change the ecp directory to ecp.old, and then restart iis services.

Before you change ecp directory, please backup the Temporary ASP.NET Files.

Hi Cara,

Thank you very much for your reply - I'll do what you're saying and post the result.

Regards,

Michael

Hello,

Is there any update?

Hello Cara,

Tell me, please how can I recreate ECP directory in IIS as I can not  use shell, it can't connect to the server:

Renaming ecp directory did not help.

P.S. I mean should I recreate ecp directory both in the Default Web Site and Exchange Back End?

Hello,

You should recreate ecp directory in the default web site.

Before you recreate epc virtual directory, I consider you should solve your EMS issue. For your EMS issue, please refer to the following KB to solve it. (Note: Based on my known, I consider it also applies to exchange 2013)

http://support.microsoft.com/kb/2028305

In kb, under resolution, the DLL location for this module should point to C:\Program Files\Microsoft\Exchange Server\v15\Bin\kerbauth.dll.

Hello,

Thank you for the reply. I've checked all the options described in this article http://support.microsoft.com/kb/2028305

- all of them are ok.

But the main question for me is WHAT could cause such issues on the server that has NOT any load - it's just a test server that's beeing started once a day for several hours. It has only 3 mailboxes including administrator's one...
