Remote Access Error 661: Modem.inf COMMAND (107061)


The information in this article applies to:

  • Microsoft Windows NT Server 3.1
  • Microsoft Windows NT Workstation 3.1
This article was previously published under Q107061

SYMPTOMS

After you edit Windows NT Remote Access MODEM.INF, PAD.INF, or SWITCH.INF file, you receive the following error message:
Error 661: The device .INF file is missing a command.

CAUSE

The "command" and "command_init" line in the .INF files must be in all uppercase. If they are written lowercase or mixed case, you will receive the above error message.

RESOLUTION

All command lines in MODEM.INF, PAD.INF, and SWITCH.INF should be in all uppercase. They must be listed as "COMMAND" and "COMMAND_INIT" exactly.

Usually, Windows NT configuration files are not case-sensitive. No other commands lines in the RAS .INF files are case sensitive. However, as a precaution, you should specify all your RAS commands in upper case.

STATUS

Microsoft has confirmed this to be a problem in Windows NT and Windows NT Advanced Server version 3.1. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
