Serge,

tnsping works fine:

C:\oracle\ora92\bin>tnsping TEST

TNS Ping Utility for 32-bit Windows: Version 9.2.0.1.0 - Production on 14-OCT-20
05 14:40:17

Copyright (c) 1997 Oracle Corporation.  All rights reserved.

Used parameter files:


Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)
(HOST = INSWITCH-APP)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = TEST)))
OK (30 msec)

And yes, the DSN is defined in Control Panel\Administrative Tools\Data Sources.
    Sebastian-
