New Installation of Windows NT 4.0 Results in STOP 0x00000050

Trying to perform a new or parallel installation of Windows NT 4.0 may result in the following error: NOTE: The first argument in the parenthesis may differ slightly.

This error may occur if you try to perform a clean installation of Windows NT 4.0 using a modified Disk 2 of the three disk installation set that contains 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.
  
  -or-
• 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 a common scenario when trying to repair a computer running Windows NT 4.0 Service 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.
