Not directly a ZEN imaging problem, just an FYI for a major problem we
had developing our Windows XP SP2 ZEN images that turned out to be a
Microsoft problem. You have to call microsoft for the hotfix and they
will email it to you. Although I haven't tested the patch yet,
according to the google groups post I found, it should work. I will
post my result here when done.

The symptoms are:

Customizations to the Default User account are missing.

Customizations to the Administrator account are present in a new
user's account when the user logs on to Windows XP.

Customizations made directly to the Ntuser.dat file are missing.
