                          I installed oracle 12c pn windows following the defaults settings... I end up with ORCL and ORCLPDB...

I can connect to ORCLPDB using EZCONNECT via CONN system/password@//localhost:1521/ORCLPDB . Then I added a service name in my tnsnames.ora like this : 

    ORCLPDB =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
        (CONNECT_DATA =
          (SERVER = DEDICATED)
          (SERVICE_NAME = orclpdb)
        )
      )

But when I try connect system/password@ORCLPDB I get the following error :

>ORA-12154: TNS:could not resolve the connect identifier specified

This is strange because lsnrctl services has the following entry :

>Service "orclpdb" has 1 instance(s).
  Instance "orcl", status READY, has 1 handler(s) for this service...
    Handler(s):
      "DEDICATED" established:0 refused:0 state:ready
         LOCAL SERVER

What should I do ?
