After applying NOV SU on 2016 CU23, getting this error on Powershell launch
Connecting to remote server exch-2016-mbx01.lab2016.local failed with
the following error message : WinRM cannot process the request. The following error with errorcode 0x8009030e occurred
while using Kerberos authentication: A specified logon session does not exist. It may already have been terminated.
Possible causes are:
-The user name or password specified are invalid.
-Kerberos is used when no authentication method and no user name are specified.
-Kerberos accepts domain user names, but not local user names.
-The Service Principal Name (SPN) for the remote computer name and port does not exist.
-The client and remote computers are in different domains and there is no trust between the two domains.
After checking for the above issues, try the following:
-Check the Event Viewer for events related to authentication.
-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or
use HTTPS transport.
Note that computers in the TrustedHosts list might not be authenticated.
-For more information about WinRM configuration, run the following command: winrm help config. For more
information, see the about_Remote_Troubleshooting Help topic.
