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:


 * Run Registry Editor (REGEDT32.EXE).
 * 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.
