My problem is that windows 2000 ignor my winnt.sif. I Made my Bultibott dvd exactly like in the guide from flyakite. Windows xp use the sif file and install Unattended without any problems. I edited the .dat ,setupldr.bin and the txtsetup.sif file exactly as shown in the guide. my winnt.sif for 2000: [Data] AutoPartition =0 MsDosInitiated = "0" UnattendedInstall = Yes [unattended] DriverSigningPolicy=Ignore UnattendMode=FullUnattended OemSkipEula=Yes OemPreinstall=Yes TargetPath=\WINNT UnattendSwitch="Yes" WaitForReboot="No" OemPnPDriversPath="DRIVERS\000_intel_cs;Drivers\001_intel_network;Drivers\003_ati;Drivers\004_sound;Drivers\005_printer" UnattendSwitch=Yes [GuiUnattended] AdminPassword=xxxxxxx AutoLogon=Yes AutoLogonCount=1 OEMSkipRegional=1 TimeZone=110 OemSkipWelcome=1 [userData] ProductID = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx [Display] BitsPerPel=24 Xresolution=1024 YResolution=768 Vrefresh=72 [LicenseFilePrintData] AutoMode=PerServer AutoUsers=20 [GuiRunOnce] Command0=%systemdrive%\install\install.cmd [identification] JoinWorkgroup=ARBEITSGRUPPE [Networking] InstallDefaultComponents=Yes
