ORA-12514 and UNKNOWN status

Question

Hi,
on 10.2.0.3 on Win can not connect to DB by :
sqlplus user/password@MYDB
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor.
lsnrctl status  gives :
Service "MyDB.server.LOCAL" has 1 instance(s).
  Instance "MYDB", status UNKNOWN, has 1 handler(s) for this service..
But tnsping MYDB is OK.
I can connect with :
set ORACLE_SID=MYDB
sqlplus / as sysdba
Any idea ?
Thank you.

Since every connection request to the listener gets logged, listener.log file will contain a line with 12514 as status code.

TNS-12514: TNS : listener does not currently know of service requested in connect descriptor
connection request was for "MYDB" service but listener only know about service name below
>Service "MYDB.serverdomaine.LOCAL" has 1 instance(s).
which is NOT named "MYDB"!
so either change listener or change requested Service name so they match each other!
