Remotely Manage a Workgroup Hyper-V Host

Remote Hyper-V management is simplest when the client and host are domain joined. For a workgroup or non-domain host, Microsoft documents additional WinRM/credential delegation configuration. Apply this only on trusted management networks.

On the Hyper-V host

Enable-PSRemoting
Enable-WSManCredSSP -Role Server

On the management computer

Set-Item WSMan:\localhost\Client\TrustedHosts -Value "HVHOST01"
Enable-WSManCredSSP -Role Client -DelegateComputer "HVHOST01"

Use the host name where possible. If you must use an IP address, use a documentation/test address such as 192.0.2.10 in written examples, not a real internal address.

Credential delegation

Microsoft also documents the Group Policy setting Allow delegating fresh credentials with NTLM-only server authentication for workgroup scenarios. Restrict the delegation target to the specific wsman/hostname entry rather than using a wildcard.

Verification

Open Hyper-V Manager, choose Connect to Server and connect using the intended administrator credentials. After testing, review TrustedHosts and CredSSP settings and remove entries that are no longer needed.
