Auto Sync Windows XP time on Boot

Question

I have an old PC with a defective CMOS battery, and every time the clock is reset, I have to log as admin in Windows XP and set the date manually, then I can sync from the server. As this computer has parental control to protect children to use this computer between some periods, I would like to perform this date/time sync automatically on boot. How can I do this?

Answer 1

I found Karen's Time Sync, configured to start and sync on logon, it seems to do everything I need.

Edit: in fact, Karen's Time Sync does not seem to be able to sync when a limited user logs in, so I replaced it with NetTime, that works perfectly !
