Get-Ipconfig

This script is a really old PS v1 script that I put together for reading network configurations remotely. It uses a mix of WMI and remote registry reading (to get primary dns suffix). It gives roughly the same information that ipconfig /all will give

Example

PS C:\> get-ipconfig localhost
