I'm new to this, but I have most of the unattended install working. I've got all the basic like serial key, computer name, formatting/converting to NTFS, things like that. However, if I want to run a batch file after installing and copy files to the computer and make registry tweaks these don't work. BTW, I'm using MS Virutal PC 2004 to test my iso's. I have OemPreinstall set to yes. My directory structure is like so...\I386\$OEM$\C\firstrun. Inside the firstrun folder I have the batch file and registry file as well as a couple of folders containing files I want copied over. Am I missing something obvious somewhere in my sif file? Here is the winnt.sif code: ;SetupMgrTag [Data] AutoPartition=1 MsDosInitiated="0" UnattendedInstall="Yes" [Unattended] UnattendMode=FullUnattended Repartition=Yes FileSystem=ConvertNTFS OemSkipEula=Yes OemPreinstall=Yes UnattendSwitch=Yes TargetPath=\WINDOWS [GuiUnattended] AdminPassword=<removed> EncryptedAdminPassword=Yes OEMSkipRegional=1 TimeZone=20 OemSkipWelcome=1 AutoLogon=Yes AutoLogonCount=1 [UserData] ProductKey=<removed> FullName="xxxxx" OrgName="xxxxx" ComputerName=xxxxx [Components] msnexplr=Off zonegames=Off OEAccess=Off [URL] Home_Page=xxxxx [Identification] JoinWorkgroup=WORKGROUP [Networking] InstallDefaultComponents=No [RegionalSettings] LanguageGroup=1 Language=00000409 [IEPopupBlocker] AllowedSites=xxxxx [Branding] BrandIEUsingUnattended=Yes [Proxy] Proxy_Enable=0 Use_Same_Proxy=0 [NetAdapters] Adapter1=params.Adapter1 [NetClients] MS_MSClient=params.MS_MSClient [NetServices] MS_SERVER=params.MS_SERVER [NetProtocols] MS_TCPIP=params.MS_TCPIP [params.MS_TCPIP] DNS=No UseDomainNameDevolution=No EnableLMHosts=Yes AdapterSections=params.MS_TCPIP.Adapter1 [params.MS_TCPIP.Adapter1] SpecificTo=Adapter1 DHCP=Yes DNSServerSearchOrder=<removed> WINS=No NetBIOSOptions=0 [params.Adapter1] INFID=* [GuiRunOnce] %systemdrive%\firstrun\firstrun2.bat When I run this, it doesn't appear to ever logon one time, because as soon as I manually logon it gives me an error saying it can run the batch file because it isn't there. It isn't there, because the files were not copied over. Thanks for the help.
