Chris,
This is frequently caused by a problem with the
tnsnames.ora (mismatched parentheses, invalid
oracle_home, etc...). There are several docs on
metalink regarding this error for various
configurations and releases.
As others have suggested, you might also enable net8
tracing as that is most likely to reveal the real
culprit.
