I have one Windows XP machine (sp3) in my domain that keeps losing 1 hour. When I open up the clock properties I notice that the time is set to "Eastern Standard Time". ALL other PC's in domain are set to "Eastern Daylight Time". My guess is that this is what's causing the time to change? Problem is that I don't see where I can change it to Eastern Daylight Time".
Any input would be greatly appreciated. Hopefully it is just something simple that I am over looking.
