You can use Windows PowerShell remoting with the WS-Management protocol to connect to the computers in a domain from a computer that is a member of a workgroup, not a domain. However, some preparation is required. This topic explains how to configure a workgroup-based computer for Windows PowerShell remoting to a domain.
If you try to establish remote connections from a workgroup-based computer that is not correctly configured, Windows PowerShell generates the following error message.
ERROR: 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.
To configure a workgroup-based computer for remoting
Configure the computer for HTTPS transport or add the names of the remote (domain-based) computers to the TrustedHosts list on the local (workgroup-based) computer. For more information, see How to Add a Computer to the TrustedHosts List.
Verify that a password is set on the workgroup-based computer. If a password is not set or the password value is empty, you cannot run remote commands. To set password for your user account, in Control Panel, use User Accounts.
Use the Credential parameter in all remote commands. This is required even when you are submitting the credentials of the current user.
