Have you used the SQL-net Easy Config to generate your configuration files? If so, try using the TNSping facility to ping the instance. If you can't ping the instance you can't sign on, investigate why. Make sure you're going to the right place (check the address etc.), can you ping the server itself (if using IP)?
