Hello. I'm new to the board and also a beginner to "Unattended Windows" so forgive me if I'm asking an already answered question. I tried searching, but couldn't figure out my problem, so my only option is to ask here. I've mostly figured out and configured everything how I want it to, but TimeZone= doesn't seem to want to set properly to my prefered Time Zone, which is; "((GMT) Greenwich Mean Time: Dublin, Edinburgh, Lisbon, London)" rather it stays at "((GMT-08:00) Pacific Time (US and Canada); Tijuana)" Here is my WINNT.SIF file; ;Savas XPCD09SAV04 [Data] AutoPartition=1 MsDosInitiated=0 UnattendedInstall=Yes [Unattended] KeyboardLayout="United Kingdom" OemPreinstall=No UnattendMode=ProvideDefault [GuiUnattended] AdminPassword="*" ProfilesDir="%SystemDrive%\Users\" TimeZone=085 [UserData] FullName="Savas" ProductKey=* [RegionalSettings] Language=00000809 LanguageGroup=1 [Identification] JoinWorkgroup=GROUP23 [Components] msmsgs=off msnexplr=off I also changed TXTSETUP.SIF. So that United Kingdom is properly set as Location/Language. (I don't really know what UnicodeCasetable = l_intl.nls,0809 does exactly, though.) DefaultLayout = 00000809 UnicodeCasetable = l_intl.nls,0809 I think I need to manually edit the default Time Zone within TXTSETUP.SIF, but I just can't find it.
