Article: Q254608
Product(s): Microsoft Windows NT

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

On a computer with Routing and Remote Access Services (RRAS) installed,
configuring a phonebook entry or a dial-on demand (DOD) entry for callback
causes additional devices to be created as follows:

  U.S. Robotics 56K Message V.34 only (COM1)
  U.S. Robotics 56K Message V.34 only (COM1) 12345
  U.S. Robotics 56K Message V.34 only (COM1) 12345
  U.S. Robotics 56K Message V.34 only (COM1) 12345

This causes callback not to work because it is unable to match the originally
selected name against a valid entry.

CAUSE
=====

This problem only occurs on computers with RRAS installed.
