We have recently, since Daylight Savings Time happened, had several users, which suddenly cannot log in during their assign login time... typically 07:00am to 07:00pm. Login times assigned to Active Directory.
Global Policy is set to activate NTP Client and get time from tick.usno.navy.mil. Time in all domain controllers and PCs are correct. The odd thing is that it did not happen at the time change, but has manifested itself late last week and this week. Never been a problem before. Have check the PCS and the DAYLIGHT SAVINGS TIME box is checked. Very Odd. Any ideas? Please advise.
PDC is Windows 2003 Server R2

PCs all running XP Pro SP3 with current corrections
