"Line Non-Operational" in Remote Access Service Monitor (138721)
The information in this article applies to:
- Microsoft Windows NT Server 3.5
- Microsoft Windows NT Server 3.51
This article was previously published under Q138721 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.
- 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.
