A strange problem and annoying for the user: one of our client XP workstations, joined in a Small Business Domain, has a problem with it's system clock.
We've replaced the motherboard BIOS battery, changed NTP settings and of course tried setting the time manually. Still the clock is not synchronizing with the network/NTP settings. After a day of setting the clock the time can differ for over an hour or even a day.
Someone knows what this could be or does someone know a simple tool that can run as a background services for clock synchronization?
