Writing the Query

You've seen the whole associated class thing in action, but I want to start fresh with a new example and walk you through the entire query- and script-creation process. In the last chapter, I showed you how to set all the network adapters on a computer to use DHCP. In this chapter, I want to be more specific, and only modify the properties of a specific network adapter within the computer. More specifically, I want to

• Read a list of computer names from a text file

• Connect to WMI on each computer and locate the network adapter named "Local Area Connection"

• Ensure that each configuration for that adapter is set to use DHCP

It seems like the following query should do what I want.

ASSOCIATORS OF

{Win32_NetworkAdapter.NetConnectionID="Local Area Connection"}

WHERE

RESULTCLASS = Win32_NetworkAdapterConfiguration

That should pull all Win32_NetworkAdapter instances where the NetConnectionID is "Local Area Connection," and then retrieve the associated Win32_NetworkAdapterConfiguration instances.
