• Windows Patch 3033929

I am a systems analyst and even I had this issue. Often we 'techies' head for the really simple stuff first then jump to the really complex stuff second. The fix for me was pretty simple.

On my Windows XP Pro systems there was a default option under the 'Date and Time Properties' that required a simple unchecking of a box. Ofcourse check the time zone, check or uncheck the DST box (it had no affect on my systems either way). The fix for me was a third tab 'Internet Time.' The box was checked next to 'Automatically sync with an Internet time server', UNCHECK that box then set your time. I have Never manually set this option it must have been part of a baseload, but I'll pay attention to it next time. Hope this helps.

Windows Patch 3033929

I am new as a network admin and I have run into this problem on only four computers in our whole company. I have tried everything including setting the time manually, checking and unchecking to adjust for daylight savings time. I know the server is set correctly and we also have the DC set correctly or this would affect everyone and not just these few people. I tried going into the properties of the date and time and did not find the third tab. How would one go about fixing this if all else has failed to this point?
