There are certain scenarios that could cause and XP box to not synchronize with an Internet time server even though it is set to automatically synchronize.
This problem may occur in the following scenario:
• A scheduled task automatically resumes the computer from standby or from hibernation.
• The computer automatically goes on standby or into hibernation again.
For example, a computer that is running Windows XP Media Center Edition 2005 automatically resumes from standby to record a scheduled show. Then, the computer automatically goes on standby after the recording has finished. In this example, the computer may not synchronize the clock with an Internet time server until the computer restarts.
