    Re: NTVDM CPU Has Encountered an Illegal Instruction

    If you want to fix this problem then replace the Command.com file in the Winnt\System32 folder with the same file from another computer that is running Windows NT Workstation 4.0 or Windows NT Server 4.0, and then make sure that there are no Command.com files dated 7/11/95 on the computer. You can also replace the Command.com file on the computer with the same file on the Windows NT installation CD-ROM.
