Explorer.EXE - Entry Point Not Found error when installing XP SP2 with /quit switch

[Andre]

I configure my SMS server to do a quit deployment of SP2 to a test XP
system. I used the /quit and /forcereboot switches to deploy, but the
computer does not reboot. When I try to log in after the installation,
the computer displays an error message Explorer.EXE - Entry Point Not
Found. EventID:26. After displaying the message the computer reboots
automatically. Does anyone know why the computer is doing that?

I'm not really sure how your machine got into that state, but it's been my
experience that a repair install is usually needed to get out of this:
