How To Connect Remotely From a WORKGROUP-Server Core (Server Manager)

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.

When the local computer is not in a domain, the following procedure is required for remoting.

    1. Configure the computer for HTTPS transport or add the names of the

       remote computers to the TrustedHosts list on the local computer.

       For instructions, see "How to Add a Computer to the TrustedHosts

       List" below.

    2. 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, use User Accounts in Control

       Panel.

    3. Use the Credential parameter in all remote commands.

 

       This is required even when you are submitting the credentials

       of the current user.

HOW TO ADD A COMPUTER TO THE TRUSTED HOSTS LIST

**Note: You need to add on both Server E.g. Full Windows 2008 R2 (Management Server) and Server Core 

 Caution: The value that you set for the TrustedHosts item affects all users of the computer.      

To view the list of trusted hosts, use the following command:          

get-item wsman:\localhost\Client\TrustedHosts      

You can also use the Set-Location cmdlet (alias = cd) to navigate though the WSMan: drive to the location. For example: "cd WSMan:\localhost\Client; dir".     

 To add all computers to the list of trusted hosts, use the following command, which places a value of * (all) in the ComputerName          

 set-item wsman:localhost\client\trustedhosts -value *      

You can also use a wildcard character (*) to add all computers in a particular domain to the list of trusted hosts. For example, the following command adds all of the computers in the Fabrikam domain to the list of  trusted hosts.          

set-item wsman:localhost\client\trustedhosts *.fabrikam.com  

To add the IP addresses of particular computers to the list of trusted hosts, use the following command format:         

 set-item wsman:\localhost\Client\TrustedHosts -value       

For example: set-item wsman:\localhost\Client\TrustedHosts -value 172.16.0.0
