• Microsoft Windows NT Server version 4.0
• Microsoft Windows NT Workstation version 4.0
• Microsoft Routing & 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:

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
