PowerShell 2+
Many older DCOM-based commands require a “Remote Administration Firewall Exception” to access remote systems. This includes cmdlets like Get-WmiObject.
One easy way of enabling this is to run the following command in a PowerShell with Administrator privileges:
netsh firewall set service remoteadmin enable
Although this command is considered deprecated, it is still working and one of the easiest ways of configuring the firewall.
