Choose Close to terminate the application.
When you click Close, you may receive several similar error messages.

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.
