# Listener Configuration, SPX Protocol

SPX identifies a listener protocol address by a network-wide unique service name. A SPX service name identifies a network service. Make sure that you are entering a service name that matches the SPX protocol definition of a listening location.

Use the standard SPX service name of <computer_name>_lsnr:

Select this option to listen on the default service of `<computer name>_lsnr`.

Use another SPX service name:

Select this option to specify another service to use other than `<computer name>_lsnr`.

Make sure that there is no other services on the entire network that have the same name. If there is another service with the same name, there will be conflicts until one of the identical service names are changed. This is a frequent problem on SPX networks.
