Thanks for the reply. I eventually re-found that article. I was pretty unimpressed with it though. Perhaps because the first two entries in PIC1.jpg are wrong.
They have a login item of "c:\checkinapp\shitchcheckinappstart". That is neither the location, nor the name, of the current check-in app. They also specify a proxy server. I didn't look at much past that.
I am using Microsoft's Steady State. Steady State and sysprep do not play well together, so I put a RunOnce entry for NewSID in the image. It seems to work well.
