To run powershell commands on a machine from a remote machine we have to add the remote machine to the trusted hosts list of the host machine.

I am adding machine A to machine B's trusted hosts using the following command :

winrm set winrm/config/client ‘@{TrustedHosts="machineA"}’

How to add more machines say machine C, machine D to trusted hosts list of machine B?

I prefer to work with the PSDrive WSMan:\.

Get TrustedHosts

Get-Item WSMan:\localhost\Client\TrustedHosts

Set TrustedHosts

provide a single, comma-separated, string of computer names

Set-Item WSMan:\localhost\Client\TrustedHosts -Value 'machineA,machineB'

or (dangerous) a wild-card

Set-Item WSMan:\localhost\Client\TrustedHosts -Value '*'

to append to the list, the -Concatenate parameter can be used

Set-Item WSMan:\localhost\Client\TrustedHosts -Value 'machineC' -Concatenate
