Here is the answer at Microsoft's web site


CAUSE


This behavior can occur if you use an incorrect version of the Command.com file. For example, this issue is known to occur if you use a Command.com file included in Microsoft Windows 95, dated 7/11/95.

RESOLUTION


To resolve this issue, 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.
