This may be a dumb idea, but if your entry looks like this
you could try changing it to this
or vice-versa

If I use SQL*Plus for Windows version 9, it works.  I copied the tnsnamed.ora 
from the Ora9 HOME to the Ora10 HOME, so the connect info should be the same.
DB and listener are up.

Thanks for any thoughts.

        The error means that you've connected to a listener at the host/port 
specified in your connect string, but the listener you've connected to doesn't 
recognize the value of SERVICE_NAME specified in the connect string.  
        On the database server, where the listener is running, if you do a 
'lsnrctl services', is the service you're trying to connect to listed there?  
Also on the database server, what if you connect to the database with "/ as 
sysdba", and do 'alter system register;"?  Then try the lsnrctl command again, 
is the service listed?  Did that fix the problem?  If not, are there multiple 
listeners on that database server?  Maybe you're connecting to the wrong one, 
and it doesn't support that service? 
        Hope that helps,

        SQL*Plus <>  is installed on my laptop and I 
want to use it to connect to as many databases as I can. (mainly 9i variants)  
I have updated the tnsnames.ora in the 10g home to contain all the entries, and 
when I use the command-line tnsping, it resolves the names, but when I use 10G 
SQL*Plus for Windows, it tells me 

        ORA-12514: TNS:listener does not currently know of service requested in 

        SP2-0640: Not connected

        What am I missing?
        Bonus points if you can tell me how to connect 10g EM Database Control 
to other databases (i.e. especially 9i)
