I'm having issues with some machines now that I thought I had sysprep finally working like I wanted. It's not all machines, but two models that I've found issues with are Dell Optiplex GX520 and Dell Latitude E5510. From playing around with my snapshots, it seems to be an issue with using the ACPI Hal to create the sysprep image. I went back to a previous snapshot (almost 4 months) and copied my existing sysprep setup files. The only difference, that I can tell, is the Hal, it was a uniprocessor hal. The bad thing is we have a few hundred of each type. After I image the machine, the first windows screen (with windows logo) just scrolls and scrolls and after a couple of minutes, just stops. I've tried using bootloging, but it doesn't even create the file. I wanted to try my current image, but it looks like I can only upgrade ACPI to Uniprocessor by reinstalling. If anyone has any suggestions, I'd be most appreciative. Thanks Phillip Allen Marion School District 1
