Automated reboot and login as admin

Hello,

I have a package to install on a Windows XP pro system which I am trying to automate for non admin privleged users. After the product installs, a reboot is required and an administrator must logon for the install to complete itself.

Can I automate the process of having the machine reboot, logon as a local admin and then logoff while keeping the user “out” while this occurs? After this process completes the user can log back on as themselves and continue to work.

Thanks for thehelp…
