That error is a common one. It should be documented in your SQL*Net manual or in the oerr utility. It means that you cannot find the correct database instance. This is usually a problem in the .ora files in the orant/network/admin directory. If you have "oracle names" running then this should be a slam dunk but that seems unlikely given the error. More likely you will have to modify the tnsnames.ora file. There is a configuration utility that does this. You will have to know what your database instance name is. If you are on the same machine that you installed Oracle on, you might ORCL as the instance name.
Good luck,
Paul
