Ejecuto una instancia de Oracle 11g localmente en mi máquina de desarrollo y puedo conectarme a la instancia local directamente a través de SqlPlus:

Pero no puedo conectarme a través del oyente:
c:\>sqlplus -L "user/pw@(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = XE)))"

ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
SP2-0751: Unable to connect to Oracle. Exiting SQL*Plus
Del mismo modo, si me conecto a través de SqlDeveloper me sale un error (aunque ORA-12505, TNS:listener does not currently know of SID given in connect descriptor).
Esta instancia ha sido estable y funciona bien durante un año o más hasta hoy, un lunes por la mañana. Nuestra TI corporativa a veces impulsa nuevas políticas y actualizaciones durante el fin de semana, por lo que supongo que algo ha cambiado, pero no he podido averiguar qué.
He reiniciado el servicio y el oyente varias veces, el registro del oyente no da ninguna pista.
El oyente parece estar bien:
