TITLE   :RAS or RRAS Server Fails to Answer Incoming Calls
PRODUCT :Microsoft Windows NT
PROD/VER:WinNT:4.0
OPER/SYS:
KEYWORDS:kbnetwork kbWinNT400sp4fix

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

 - Microsoft Windows NT Server version 4.0 
 - Microsoft Windows NT Workstation version 4.0 
 - Microsoft Routing and Remote Access Service Update for Windows NT Server version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

Your Windows NT Remote Access Service (RAS) Server or Routing and Remote Access
Service (RRAS) server fails to answer incoming calls on a particular port. You
have your RAS or RRAS server configured to answer calls after a specific number
of rings.

For additional information, please see the following article(s) in the Microsoft
Knowledge Base:

ARTICLE-ID: Q170825
TITLE : RAS Auto-Answer Behavior in Windows NT

CAUSE
=====

A RAS client attempted to connect to your server and the connection was
interrupted before the specified number of rings for the RAS or RRAS server
could occur.

For example, you have your server configured to answer after five rings. A client
dials and the call is interrupted before it reaches the fifth ring. The server
will not answer any more calls on that port until the RAS or RRAS server is
restarted.

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,
please see the following article in the Microsoft Knowledge Base:

Server 4.0, Terminal Server Edition. This problem was first corrected in Windows
NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition
Service Pack 4.
