I am trying to set the Network Address of a USB C docking station attached to a remote system to match that of the systems primary NIC. When I run my script I get an error message stating “Cannot bind argument to parameter ‘Name’ because it is an empty string.” When I perform Write-Host $DockName is returns the string value I am looking for but will not complete the assigned task. What am I missing?
