WSUS

I looked up this document just the other Day!

Configure your settings to "Notify for download and notify for install"

To get a PC to look for updates manually, type "wuauclt.exe /detectnow" from the command prompt.

As far as redirecting the Windows Update site to WSUS, the WSUS doesn't have a "website" for client PCs to go to from internet explorer to scan for updates. I know you can disable Windows Update website access through group policy though.

That being said, here is a link to the WSUS forum. You might find better info there.

I have a group policy that points all of the clients to the WSUS server. In there you also specify if the client will only download updates or install and all the other options. I have mine set to install at 3:00am everyday.

You also need to configure WSUS to sych with Microsoft on a set time schedule. Also set what application updates you want WSUS to download. You then have to approve updates.
