Scripting network configuration

I’m working on a project to reconfigure a subnet, and I need to update the network configuration of all the hosts in that subnet. I decided that it’s time to really put PowerShell to work. The Script Center has some good source material, including a PowerShell script to enumerate network configuration and a VB Script to update it. Cross-referencing these with the MSDN details of the Win32_NetworkAdapterConfiguration WMI class, I think I have all the pieces I need.

Here’s a sample:

$computer = "."
$all_nics = get-wmiobject -class "Win32_NetworkAdapterConfiguration" -computer $computer -filter "IPEnabled=TRUE"

foreach ( $nic in $all_nics ) {

	write-host "IP Address      : " $nic.IPAddress

	write-host "MAC Address     : " $nic.MACAddress

	write-host "Default Gateway : " $nic.DefaultIPGateway

	write-host "Subnet Mask     : " $nic.IPSubnet

}

I’ll be working with the EnableStatic and SetGateways methods to make the changes.
