Powershell: The WinRM Client Cannot Process the Request


Error when running New-PSSession command:

Connecting to remote server failed with the following error message : The WinRM client cannot process the request. The authentication mechanism requested by the client is not supported by the server or unencrypted traffic is disabled in the service configuration. Verify the unencrypted traffic setting in the service configuration or specify one of the authentication mechanisms supported by the server. To use Kerberos, specify the computer nameas the remote destination. Also verify that the client computer and the destination computer are joined to a domain. To use Basic, specify the computer name as the remote destination, specify Basic authentication and provide user name and password. Possible authentication mechanisms reported by server: For more information, see the about_Remote_Troubleshooting Help topic.

+ CategoryInfo : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException

+ FullyQualifiedErrorId : PSSessionOpenFailed



One common cause of this error is that basic authentication is not enabled for the Powershell web application on the Exchange Server. 




Go to IIS on your Exchange Server, open the PowerShell directory and select the "Authentication" feature. Enable basic authentication.
