call me old school.. But sysprep is waste of time -- much faster to get baseline machine and create images...
Considering sysprep has existed since Windows 2000, someone is just being lazy. If you said Ghostwalker, that's old school and hasn't worked in years.
Your GPOs broke because the patch addressed Keberos authentication and GPO.

Since you have the same SID on all those boxes, whomever grabbed the token first won. All my clients didn't have a single problem with this. Between the hundreds of domains, I haven't heard a single person complain about GPOs. And we have 15 domains just for our corp environment, not to mention the 50 or so with customers VMs.
In other words, work shit right and shit works right.
