ORA-12203: TNS:unable to connect to destination
 *Cause: Invalid address specified or destination is not listening.
 This error can also occur because of underlying network or network
 transport problems.
 *Action: Verify that the net service name you entered was correct.
 Verify that the ADDRESS portion of the connect descriptor which
 corresponds to the net service name is correct.  Ensure that the
 destination process (for example the listener) is running at the
 remote node.

Regards
Michel

Please veryfy that the TNSNAMES.ORA are equal. Post the entry for the database you are trying to reach.

Also, post the output from the command
tnsping <database_you_are_trying_to_reach>

like this:
TNS Ping Utility for 32-bit Windows: Version 11.1.0.6.0 - Production on 21-SEP-2009 02:06:23

Copyright (c) 1997, 2007, Oracle.  All rights reserved.

Använde parameterfilerna:
c:\devsuitehome_1\NETWORK\ADMIN\sqlnet.ora


Använde adaptern TNSNAMES för att tolka aliaset
Attempting to contact (DESCRIPTION= (ADDRESS= (PROTOCOL=TCP) (HOST=the_computer) (PORT=1521)) (CONNECT_DATA= (SERVICE_NAME=the_db_you_are_trying_to_reach)))
TNS-12541: TNS: ingen lyssnare


In this case, there were no listner. Since I did not start it. You should, however, be able to get a response from the database. recognized via [OK] marks.
