PS Remoting to Home Server

I wanted to PowerShell remote to my home server, but as it is – for the good reason, that it is impossible – not in the domain of my PC, I have to add it to TrustedHosts.

This is my story.

First, I enabled PS remoting on the home server with a simple


Next, I attempted to access the server

enter-pssession server -cre server\administrator

By doing so, I received a very long error message.

I tried with –authentication negotiate. This reduced the error message to 10 lines ;) It told me to configure TrustedHosts with Winrm.cmd.

I looked at Winrm.cmd, but that looked very complicated and this is at the end of the day. Luckily, the WSMAN drive popped up in my mind. I switched to my administrative account and did this

PS C:\Users\user> cd wsman:
PS WSMan:\> dir


ComputerName Type
------------ ----
localhost Container

PS WSMan:\> cd .\localhost
PS WSMan:\localhost> dir

WSManConfig: Microsoft.WSMan.Management\WSMan::localhost

PS WSMan:\localhost> cd .\Client
PS WSMan:\localhost\Client> dir

WSManConfig: Microsoft.WSMan.Management\WSMan::localhost\Client

PS WSMan:\localhost\Client> Set-Item .\TrustedHosts server

WinRM Security Configuration.
This command modifies the TrustedHosts list for the WinRM client. The computers in the TrustedHosts list might not be authenticated. The
client might send credential information to these computers. Are you sure that you want to modify this list?
[Y] Yes [N] No [S] Suspend [?] Help (default is "Y"): y
PS WSMan:\localhost\Client>

Back to my standard user

194 WSMan:\localhost> enter-pssession server -cre server\administrator
[server]: PS C:\Documents and Settings\Administrator\My Documents>

and it worked.


Happy remoting
