Is this a new install?
Can you query tables with Toad?
Can you connect using sqlplus?

For starters, disable your local firewall and try.

>>Can you query tables with Toad?  Yes

These mean the opposite.  If you can query the tables in Toad, you are connecting to the database.  If you cannot connect through sqlplus then I wonder how you are connecting with Toad?

>>For starters, disable your local firewall and try.
 
Did you try this?  Did it change anything?

OK.  It sounds like you are having some Network Issues.

I would work with your Network Admins to help you figure them out.

If you look up the text for the ORA-12571 it mentions that you shouldn't see this error and you should contact Oracle Support.

You might try a ping loop from the client machine to the database server and see if you drop packets around the time you receive the ORA-12571.

ping -t -l 1 <dbserver_ip_address>
