you can use nLite
to set up unattended installations. i used it to slipstream a service pack (SP2) remove rubbish like msn explorer and windows messenger AND perform an unattended install. on xp. it also works for win2000. a really good program and easy to use!
hope you find it useful, it's nice being able to boot from a disk, leave the pc for an hour and have a nice fresh windows when you come back!
