Daylight saving changes – wrong time

Hi Guys,

Clocks on my XP and 2003 machines shows wrong time an hour ahead. I distributed KB931836 which by Microsoft suppose to fix problem but it does not help. What really helps is uncheck “Automatically adjust clock for daylight saving changes”. But I can not find how to distribute this setup over whole company.
Anybody else got the got the same problem?
How to fix it?
Please help!

Thanks.
Alex.
