Add Windows 10 Client to Server Manager RSAT

[Hacker26]

Hi

I’m using the RSAT on my Windows 10 Enterprise machine, so I can test and train with it. Currently I’ve set up a Windows 10 Pro VM in HyperV which is in the same subnet as the phisycal machine. I can RDP into it with no issues using it’s local IP. When I’m trying to add the Windows 10 Pro VM to the server manager, it finds the machine via IP or machine name, but when I’m adding the machine to the server manager I’m getting the following error: “WinRM Negotiate authentication Error”. When I try the option “Manage as” from the server manager dropdown, and I input the credentials, it still fails. I’ve added the VM as a trusted host to my phisycal machine via powershell. There is no DC or anything like that, it’s just a workgroup.

Does anyone know a solution? I’m obviously missing out something basic, so I’d be glad if someone could please advise.

Thanks a lot for reading!

Further to the previous post, a bit more detailed:

@Knaper-Yaden when using the following command on powershell:

Enter-PSSession -ComputerName "192.168.0.20" -Credential Admin  

I can successfully connect to the client after providing the right credentials.
If I use the machine name instead of the IP address (192.168.0.20) then I get the folowing error:

Enter-PSSession : Connecting to remote server desktop-oe9qaob 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.

    + CategoryInfo          : InvalidArgument: (desktop-oe9qaob:String) [Enter-PSSession], PSRemotingTransportException

This is basically the same error that I get when trying to add the same client to the server manager on my machine.
I’d appreciate your expert advice!
Thanks a lot!
