Hello, I am creating a fully unattended install, and when I start populating GUIRunOnce with commands (batch files to install software), it seems to stop following my .sif file. For example, if I add commands to be executed in GUIRunOnce, then after a successful XP install, it'll ask me if I would like to register with Microsoft, check for internet connectivity, and doesn't join the workstation to my domain. But, GUIRunOnce does execute my batch files. However if I don't use GUIRunOnce, everything works great, meaning it's fully unattended and joins the domain. Here are the contents of my sif file: ;SetupMgrTag [Components] chat=off msnexplr=off zonegames=off [Data] AutoPartition=1 MsDosInitiated=0 UnattendedInstall="Yes" floppyless="1" OriSrc="\\%SERVERNAME%\RemInst\%INSTALLPATH%" OriTyp="4" LocalSourceOnCD=1 [Display] BitsPerPel=32 Xresolution=1024 YResolution=768 [setupData] OsLoadOptions="/noguiboot /fastdetect" SetupSourceDevice="\Device\LanmanRedirector\%SERVERNAME%\RemInst\%INSTALLPATH%" [unattended] DriverSigningPolicy = Ignore UnattendMode=FullUnattended OemSkipEula=Yes OemPreinstall=Yes TargetPath=\WINDOWS FileSystem=LeaveAlone NtUpgrade=No OverwriteOemFilesOnUpgrade=No [GuiUnattended] EncryptedAdminPassword=No AdminPassword="mypassword" AutoLogon=Yes AutoLogonCount=1 OEMSkipRegional=1 TimeZone=%TIMEZONE% OemSkipWelcome=1 [userData] ProductKey=myproductkey FullName="User" OrgName="Organization" ComputerName=%MACHINENAME% [identification] DomainAdmin="account" DomainAdminPassword="password" JoinDomain = "MYDOMAIN" ; DoOldStyleDomainJoin=Yes [Networking] InstallDefaultComponents=Yes ProcessPageSections=Yes [RemoteInstall] Repartition=Yes UseWholeDisk=Yes [OSChooser] Description="Microsoft Windows XP Professional w/ SP2 (Unattended)" Help="Automatically installs Microsoft Windows XP Professional w/ SP2 and base applications."
