RasDial() Does Not Connect Dual Channels with Some ISDN Adapters

ID: Q200531

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0
Microsoft Windows NT Server, Enterprise Edition version 4.0

SYMPTOMS

When you use the RasDial function to initiate a Remote Access Services (RAS) connection over an Integrated Services Digital Network (ISDN) adapter, a connection to only one channel may be created (instead of a connection to two or more channels).

CAUSE

Even if the phonebook entry is configured for multiple channels and works correctly when you invoke it manually, RasDial establishes only a single-channel connection with some ISDN adapters.

RESOLUTION

Use the Rasphone.exe command-line tool to call the Dial-Up Networking phonebook. For additional information about using Rasphone.exe, click the article number below to view the article in the Microsoft Knowledge Base:
