Make Non-domain member computers get their updates from a local WSUS server

If you have a Microsoft WSUS (software update) server on your network, you can manually set a non-domain member computer to get its updates from that server instead of sucking up bandwidth by going out to Microsoft every time it checks for Microsoft updates. To do so....

Click on Start/Run
Type in gpedit.msc
Go to Computer Configuration/Admin Templates/Windows Components/Windows Update, then you have the batch of options for configuring your Microsoft/Windows updates. It's far more granular than what you get through the Control Panel. When you plug in the information for the update server, make sure it's a name that's resolvable on the client (test it by doing an 'nslookup' from the command prompt) or just use a static IP address. Be sure though that if the computer leaves your local network you'll need to clear the settings otherwise it won't get any updates.

Have fun!
