SYMPTOMS

Window NT Virtual DOS Machine (NTVDM) may not allow 16-bit applications to run after installing Windows NT on a computer where the previous operating system had a parameter of FILES=255 or greater in Config.sys file.

CAUSE

Windows NT copies the FILES= value from the Config.sys file into the Config.nt file during setup. Any value for FILES= greater than 255 copied into Config.nt will prevent 16-bit applications from starting.

RESOLUTION

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
