Exchange Management Console error: The attempt to connect to PowerShell using ‘Kerberos’ authentication failed

Admin tried to install EMC and EMS on the exchange server after installing SQL. Firstly, it’s always recommended not to have any other application other than exchange if it is a dedicated exchange box

In this case, they had an SBS server and they attempted to install everything on the box for cost effective purpose

Post installing the SQL we were getting the below error when we open EMC

The following error occurred while attempting to connect to the specified Exchange server E2010.MsexchangeGuru.com:

The attempt to connect to http://e201.msexchangeguru.com/powershell using ‘Kerberos’ authentication failed: Connecting to the remote server failed with the following error message: WinRM cannot process the request. The following error occurred while using Kerberos authentication: The network path was not found.

We tried to browse the PowerShell virtual directory and got the below error


We checked for redirection on PowerShell and it was not set

All the authentication on PowerShell VDIR looks normal

Then tried to Browse Default web site and we were getting the same error as PowerShell

On the Default wed site also there was no redirection

Tried to restore the IIS back that was taken before the SQL install and that did not help us

On the PowerShell virtual directory, we tried to replace the web.config from a working server and that did not help us much

Checked the IIS logs and got the below entry

2017-01-13 11:18:02 127.0.0.1 GET / – 80 – 127.0.0.1 Mozilla/5.0+(Windows+NT+6.1;+WOW64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/55.0.2883.87+Safari/537.36 500 0 126 518

2017-01-13 11:18:02 127.0.0.1 GET /Msexchangegiru.com – 80 – 127.0.0.1 Mozilla/5.0+(Windows+NT+6.1;+WOW64)+AppleWebKit/537.36+(KHTML,+like+Gecko)+Chrome/55.0.2883.87+Safari/537.36 500 0 126 6

Then looked into the application logs on the server and we got 2 events

    Log Name: Application

Description:

The HTTP Filter DLL C:Program FilesMicrosoftExchange ServerV14ClientAccessowaauthowaauth.dll failed to load. The data is the error

Which made me think of an issue on the server setting as the ISAPI filters could not load

Referred the article https://support.microsoft.com/en-us/kb/2619202

Compared the values between the working and non-working server for the value of Path

To get the value of path we need to follow the below steps

Open Control Panel

2.  Open the System Icon

3.  Click Advanced System Settings

4.  Click the Environment Variables button

5.  In the System Variables section, edit the variable for Path

Working set

C:ProgramDataOracleJavajavapath;%SystemRoot%system32;%SystemRoot%;%SystemRoot%System32Wbem;%SYSTEMROOT%System32WindowsPowerShellv1.0;C:Program Files (x86)Microsoft SQL Server100ToolsBinn;C:Program FilesMicrosoft SQL Server100ToolsBinn;C:Program FilesMicrosoft SQL Server100DTSBinn;C:Program Files (x86)Microsoft SQL Server100ToolsBinnVSShellCommon7IDE;C:Program Files (x86)Microsoft SQL Server100DTSBinn;C:Program FilesMicrosoftExchange ServerV14bin

We could see for the non-working in exchange we could see the value is wrong, after adding the correct value as that of the working server. Did an IIS reset and then we could open the EMC without any issue
