# Net Service Name 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 have the listener receive client requests on the default service name of `<computer name>_lsnr.`

Use another SPX service name:

Select this option to specify another service name to use other than `<computer name>_lsnr`. Ensure the listener was configured for this service name.
