I came accross the following error while remoting to a standalone computer:
WinRM cannot process the request. The following error with error code 0x8009030e occurred while using Negotiate authentication: A specified logon session does not exist. It may already have been terminated.
Because for all other computers I am using Kerberos authentication, I was not aware that the
TrustedHosts parameter was not configured (because Kerberos doesn’t need it).
To fix this issue, configure the
TrustedHosts parameter on the client computer:
Set-Item -Path WSMan:\localhost\Client\TrustedHosts -Value 'Computer1,Computer2'
Or less secure but works too:
Set-Item -Path WSMan:\localhost\Client\TrustedHosts -Value '*'
