Using an Answer File for an Unattended Installation

This article was previously published under Q136153
An answer file is a text file that is used in conjunction with Setup tobypass normal Setup prompts. An unattended installation is run byspecifying the /U switch with Winnt.exe or Winnt32.exe. For example:
WINNT /U:{Answer File} /S:{Source Files}

Windows can use the answer files:
   Product                             Default Answer File   -------------------------------------------------------   Windows NT Resource Kit 3.5         Unattend.txt   Windows NT Resource Kit 3.51        Unattend.txt   Windows 2000 Resource Kit           Unattend.txt				
The answer file can be modified with any text editor or by using SetupManager, included in the Windows NT and Windows 2000 Resource Kit.

An answer file can also be created by using Uplodprf.exe.

Note: This answer file is included with the Resource Kit for versions of Windows NT 3.5, and 3.51.

Uplodprf.exe must be run from the system you intend to profile. UPLODPRF uses the following command line syntax:
   uplodprf -p:{AnswerFile} -b- -u- -n- -r- -x -i:{inffile}				

   -p:AnswerFile  Output an answer file for use with unattended setup.				

   -b-            The boot sector will not be copied (all other processing                  is still performed.)   -u-            Do not generate a user account definition file.				

   -n-            Do not dump ACLs of files in the profile				

   -r-            Do not dump the registry key ACLs				

   -x             Do not copy files to sharedir.				

   -i:inffile     INFFILE is the file containing the instructions for                  processing the Windows NT computer for redistribution.				

The following informational messages may result after running the abovecommand. They can be ignored.
