    Exclamation TNS:could not resolve the connect identifier-ORA-12154

    Hello everybody,

    This is my problem:
    We create in oracle 10g a database with tablespace and dbf all as TEST
    In the Microsoft ODBC administrator odbcad32:

    We have set this:
    System DSN:
    the driver: oracle 10g driver
    data source name: Test_DSN
    Description:test Database
    Server Name:TEST
    Client version: 10gR1 and later

    When we test the Connection whit this:
    Server Name:TEST
    (sadmin is the default pass for the database TEST)
    the user System is activated and has sadmin set as password.

    We get this error:
    'ORA-12154: TNS:could not resolve the connect identifier specified'

    We checked the following:
    tnsnames.ora contain this line:
    Test =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.151...)(PORT = 1521))
    (SERVICE_NAME = Test)

    We cannot find the problem.
    NB: we can connect with success using toad, we give this information:
    user :system

    Thanks for helping us, as we are waiting now, and time is running up.
