"Line Non-Operational" in Remote Access Service Monitor

 Last reviewed: July 14, 1997
Article ID: Q138721
The information in this article applies to:

- Microsoft Windows NT Server version 3.5 - Microsoft Windows NT Server version 3.51

SYMPTOMS

The following error message appears in RAS Admin on your Windows NT Remote Access Service (RAS) computer: 

   Line Non-Operational

CAUSE

When a connection is made to a RAS port, the RAS service searches for the next available port. If a port is available, it queries the device to verify that its status is OK. If an error is returned, the port is listed as "Line Non-Operational" in RAS Monitor.

RESOLUTION

This error can mean that the port itself is damaged or not set up correctly.

Alternatively, this error can mean:

  • You are running out of resources:

    If this is the case, disable some or all of the ports for outgoing calls and make them incoming lines only.

    -or-

  • The registry has the wrong information:

    To see if this is the case:

    1. Run Registry Editor (REGEDT32.EXE).

    2. From the HKEY_LOCAL_MACHINE subtree, go to the following key: 

             \System\CurrentControlSet\Services\Asyncmac\Parameters

   The Ports entry may be set to a value that is less than the number of
   incoming ports available. If NetBEUI is not loaded, this entry is not
   updated properly. If this is the case, first install NetBEUI, then 
   configure RAS to use NetBEUI for dialin and restart.
