Solution


Your computer time is more than five minutes different from the ACS Server.

To resolve the issue, change your computer time to match the ACS Server Time. The system is considerate for time discrepancies within five minutes.

 To change the computer's time
  1. In the lower right corner of your monitor, double-click the clock. The Date and Time Properties window displays.
  2. Edit the time to match your time zone above.
  3. Click Apply, then OK.
