What hardware?
What operating system?
Which version and edition of 9i
Have you checked to see if the listener is started?
Have you checked to see if TNSNAMES.ORA is pointing to the right hardware and
database?
Have you checked to see if the environment variables ORACLE_HOME and ORACLE_SID are
valid?
Have you tested TNS with the tnsping executable?
Can you ping the server?
So many questions ... so few answers.
