Couple of issues that I can't quite remember when dealing with sysprep.
1) I have a couple images that aren't to be joined to our domain, yet when I set <JoinWorkgroup>WORKGROUP</JoinWorkgroup> in sysprep.xml AND in WDS I select "Do not join the client to a domain after an installation", it still ends up connecting to the domain.
2) I'm noticing in the registry, the original computer name that had been sysprepped and captured was still showing up. I used: sysprep.exe /oobe /generalize /shutdown I can't recall if this is just how it happens or if it's supposed to be like that.
