You will need to run a sysprep on the unit. Here are the
instructions, when you are ready to run sysprep it will
come up as a gui interface, choose all 4 flags at the
bottom (PnP will be available when you choose minisetup)
change to restart and click on factory.
Click Start, click Run, type cmd, and then click OK.
At the command prompt, change to the root folder of drive
C, and then type md Sysprep.
Insert the Windows XP operating system CD into the
appropriate CD-ROM or DVD-ROM drive, and then open the
Deploy.cab file in the \Support\Tools folder.
Copy the Sysprep.exe file and the Setupcl.exe file to the
Sysprep folder.
Note If you use the Sysprep.inf file, copy this file to
the Sysprep folder also. For the Sysprep tool to function
correctly, the Sysprep.exe file, the Setupcl.exe file, and
the Sysprep.inf file must all be in the same folder.
Remove the Windows XP operating system CD.
At the command prompt, type cd Sysprep to change to the
Sysprep folder.
To run the Sysprep tool, type the following command at the
command prompt:
Sysprep /optional parameter
Note For a list of parameters, see the "Sysprep
parameters" section.
If you run the Sysprep.exe file from the %systemdrive%
\Sysprep folder, the Sysprep.exe file removes the whole
folder and the contents of the folder after it finishes.
Microsoft recommends that after you run the Sysprep.exe
file on a reference computer, isolate the reference
computer from the local network where the image will be
subsequently deployed to avoid any NetBIOS conflicts. This
permits the Sysprep tool to complete the Setup program,
join the domain that is specified, and use the new
computer name that is specified in the Sysprep.inf answer
file.
