I am getting the following errors while from the lsnrctl status command:
lsnrctl status
C:\\Users\\pna105>lsnrctl stat LSNRCTL for 64-bit Windows: Version 11.
In my case the listener service would not start because it was set to listen to a VPN connection as well to other serveral interfaces.
Once I connected to the VPN, it just started.
However, @Imre's trick with "lsnrctl start" put me to the right track.
