Control-Alt-Delete (for logging in to a Windows domain).

Press ctrl-alt-fn-delete in that order. Do not release any keys until you are holding all four down.

Dorian,

It sounds like the keyboard support is not working properly. I was working on a similar setup last weekend, and until I got the keyboard drivers working properly, I had to use the USB keyboard.

1)Have you tried to reinstall the Mac Drivers CD?
2)Try going into Device Manager(through System in the control panel), find the keyboard entries under Human Interface Device. Double click on each and in the properties, uninstall the driver. Restart the computer(have a USB keyboard handy). Log in and allow windows to reditect the drivers. Make sure you have admin rights.
3)Go back to device manager, and double click on each item in Human Interface Device. Click the update driver button. Tell it that you do not want it to search, that you will choose the driver your self. You should be given a list of drivers that are compatible. If you notice an apple driver, select it and hit ok.

Do you know you can bypass the CTRL-ALT-DEL keypress to login to Win XP?
Do a search on Google, a Regitry key can be changed so it won't require it.

Interesting idea, othen then he needs to be able to log in to change the registry.

Dorian, there might be a way go get in to change that setting suggested above, but it might affect your ability to log in to your work domain.
Do you have either a local admin account you could log in with? If not, then there is a remot chance that the admin account does not have a password.
Restart the computer, pressing f8 to get into the boot options. Select on of the safe mode options. That should bypass the control-alt-delete, but you will need an admin account to log in.
