STATUS
======

Microsoft has confirmed this to be a problem in Windows NT 4.0 and Windows NT
Server 4.0, Terminal Server Edition.

This problem was first corrected in Windows NT Server 4.0 Service Pack 6 and
Windows NT Server 4.0, Terminal Server Edition Service Pack 6.

MORE INFORMATION
================

The error status returned to the callback routine in code that calls RasDial is
inaccurate. Despite the true cause of the issue, RAS returns error code 676
("The line is busy") for line-related issues. Specifically, the following
conditions result in error code 676:

 - Phone line not plugged into the modem

 - No answer

 - No carrier (voice, fax, and so on)

The proper RAS error codes for these conditions are 680, 678, 679, 677, and so
on.
