School datalab and sysprep...

Hi,

We have a datalab with 20 Dell and 20 Compaq computers. Both of these
product lines have completely equal hardware.

We have made a 'standard' install for each of these two types with
drivers, applications and settings.

Now we want to sysprep each of them and save the two images to a file
server for easy restoring later on.

First about sysprep:

Does it erase the WSUS client ID stuff too, or do I have to do this
manually?

Is it possible to specify everything in the sysprep ini file except for
the computer name so *it will ONLY ask for this property* during the
first startup (domain name is filled in from ini file). And when cliking
OK at the computer name / domain name dialog the computer is added to
the domain and the installation is complete.

Secondly, if we want to restore these images inserting a bootable CD in
the workstations and establish network contact with the disk image
storage file server and start the restore process to the local disk.
Which tools are neatest to use (and possibly in the low-budget range as
of licensing...)

Thanks for comments and tips

regards

Jake
