SYMPTOMS
A computer that is running Microsoft Windows XP may not synchronize the clock with an Internet time server. This problem occurs even though the computer is set to do this automatically.

Additionally, a message on the Internet Time tab in the Date and Time Control Panel item may state that the time was successfully synchronized with the time server, even though the time was not updated.

You do not receive notification that this problem has occurred.

Because of this problem, scheduled tasks may not run at the correct time. For example, a computer that is running Microsoft Windows XP Media Center Edition 2005 may not record a show at the correct time. Therefore, the recorded show is incomplete. Either the start or the end of the show is not recorded.



CAUSE
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.
