[Unattended] installation speed

[Nelson Witten]

Hello -

I recently got the unattended system going in a lab to test it out.  The only downside I see with the project is the length of time it takes to install the OS and applications.  For my situation it takes just about 3 1/2 hours to install Windows XP, Office, hotfixes, and a few other applications.  In 3 hours I can build 2 machines by hand.  How can I expect a user to wait 3 hours while their machine is rebuilt?  This doesn't seem reasonable.  Comparatively I can use our RIS system or use RIPREP images and rebuild a system in about an hour.

Is there something I can do to speed things up with this system?  Does it take everyone who uses this system this long to build machines?

Thanks,
Nelson W.
