Stop Powershell v2 invoke-command -ComputerName it always runing as V1

Question

I have a Win2003 running Powershell v2. If I run

Invoke-Command -ScriptBlock {$Host.Version}

then I get "Version 2.0". However, if I run

Invoke-Command -ScriptBlock {$Host.Version} -ComputerName localhost

then I get "Version 1.0"

I assume it's something to do with remote powershell but I've been unable to find the setting. Can anyone help?

NB.

WSManConfig: Microsoft.WSMan.Management\WSMan::localhost\Plugin\Microsoft.PowerShell\InitializationParameters

PSVersion            2.0

Answer 1

Remoting host was first introduced in v2, so remoting host's version is 1 (ServerRemoteHost). When you run Invoke-Command without -ComputerName you are running command in powershell.exe directly. Try to check (and compare) $Host.Name in both commands, you should see the difference.

PowerShell version is best checked with $PSVersionTable - in v1 it's absent, in any newer version it will tell you what version of PowerShell you are currently running.
