Сбой удаленного сеанса PS на сервере, не являющемся доменом

Я пытаюсь подключиться к удаленному серверу Win2008R2, не присоединенному к домену, с помощью PS с хоста Win8 (та же подсеть, это локальная виртуальная машина). Пробовал все, что смог найти, ничего не работает.

СЕРВЕР:

PS C:\Users\Administrator> winrm quickconfig
PS C:\Users\Administrator> enable-psremoting

КЛИЕНТ:

PS C:\scripts> $cred = get-credential -username "administrator" -message "Enter password"

PS C:\scripts> $sess = new-pssession -computername 10.10.106.2 -credential $cred -authentication default
new-pssession : [10.10.106.2] Connecting to remote server 10.10.106.2 failed with the following error message : The
WinRM client cannot process the request. If the authentication scheme is different from Kerberos, or if the client
computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the
TrustedHosts configuration setting. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts
list might not be authenticated. You can get more information about that by running the following command: winrm help
config. For more information, see the about_Remote_Troubleshooting Help topic.

Да, и RDP отлично работает между этими двумя хостами с одинаковыми учетными данными.

Даже это работает:

PS C:\scripts> Get-WinEvent -computername 10.10.106.2 -credential $cred
