OS: Windows XP Pro SP3

Problem: system32.dll file became corrupted. Used recovery console to install fresh copy of system32.dll from Windows XP CD. Computer boots to custom log-in screen showing background but no text fields or buttons.  The log-in screen has worked without error for the previous 2 months.  Hitting ctrl+alt+del twice does not show the standard log-in. This is true even when started in Safe Mode.

Question: Is there a way to disable/return to standard log-in via the recovery console?

My hunch: Log-in studio makes a change in the system32.dll file when you customize the log-in screen.  When I installed the fresh copy of system32.dll it replaced these modifications.  Can anyone confirm this?

Thanks a bunch!
