This error may occur if you try to perform a clean installation of WindowsNT 4.0 using a modified Disk 2 of the three disk installation set thatcontains the Setupdd.sys file from Windows NT 4.0 Service Pack 2.
To resolve this problem, do either of the following:
Replace the Windows NT 4.0 Service Pack 2 copy of the Setupdd.sys file located on Disk 2 with the original version of Setupdd.sys.
Create new floppy installation disks, by using the WINNT /OX or WINNT32 /OX commands.
Copying Setupdd.sys from Windows NT 4.0 Service Pack 2 to Disk 2 is acommon scenario when trying to repair a computer running Windows NT 4.0Service Pack 2. Although this procedure works fine for a repair or an in-place upgrade, it does not work for a new installation of Windows NT 4.0.
