Known gotchas
CIM sessions use WinRM by default; targets must have PowerShell Remoting enabled (Enable-PSRemoting) and reachable on port 5985/5986.
New-CimSession does not verify connectivity until the first query is issued; errors are per-session and can be caught individually rather than aborting the whole batch.
PSComputerName is automatically added to result objects from remote sessions, but is absent from local queries; include it in Select-Object when mixing local and remote results.
