This might sound like an old and simple topic, but I do need your help: I was using a volume license XP with SP2 CD created a network share with Setupmgr. With the same CD, I created a BartPE. Boot a machine with the PE disc and mapped (drive letter H) to the share, then run "winnt32.exe /S:H:\i386 /unattend:H:\unattend.txt". Until this point, it is all textbook steps. I got following error after I hit enter: "the setup script does not contain a valid product ID contact your system administrator for a valid product ID" Googled the error and checked my answer file, it appears: * I don't have "," in my answer file; * "UnattendedMode" is set to FullUnattended; * I toggled between "ProductID" and "ProductKey"; * I even use Ethereal to moniter the traffic between client and server and it appears client did get the whole answer file from server. Here is my answer file and appreciate if you give me som advice. ;SetupMgrTag ;[Data] ; AutoPartition=1 ; MsDosInitiated="0" ; UnattendedInstall="Yes" [unattended] UnattendMode=FullUnattended OemSkipEula=Yes OemPreinstall=Yes TargetPath=\WINDOWS [GuiUnattended] AdminPassword="password" EncryptedAdminPassword=NO AutoLogon=Yes AutoLogonCount=1 OEMSkipRegional=1 TimeZone=4 OemSkipWelcome=1 [userData] ProductKey=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx FullName="ABC" OrgName="XYZ" ComputerName=* [Display] BitsPerPel=16 Xresolution=1024 YResolution=768 Vrefresh=60 [setupMgr] DistFolder=C:\windist DistShare=windist [GuiRunOnce] Command0=%systemdrive%\APPS\appsinst.bat [identification] JoinWorkgroup=WORKGROUP [Networking] InstallDefaultComponents=Yes
