Sysprep and admin password

Archived from groups: microsoft.public.win2000.setup_deployment (More info?)

I set up a master clone to deploy w2000 on my pc's. i've
used Sysprep 1.1 and all worked well.
Now I update my master clone with new security patches,
then I applied Sysprep and create the master with Drive
Image Pro 4.0. it seems works well but
when i try to change the password admin the pc doesn't
recognize the password I entered in the sysprep setup
wizard !!

Do you have any suggestions?
thanks in advance
