Ping should verify your firewall is not a problem.

If you can ping then make sure you are parsing the correct
tnsnames.ora file with the alias you expect. Also, check the other
.ora files for any wierd settings.

I create dummy aliases with odd names to verify which tnsnames.ora is
actually being used. I change an alias on-the-fly just to make sure it
works & doesn 't work as expected, e.g. dupe an entry as foo to connect
locally successfully, then change the entry to foo2 and try foo to
make sure it fails. Then, try your remote connection test.

Good luck.

Regards,

Mike
