Hi friends. Please help me.

Is there a way to create a DSN using MS ODBC for Oracle on win2000 without installing Oracle Client. Is their a work around? Do I have other option?
This is my objective. I would like a few co_worker using their workstation to hit a Oracle DB to learn web db development. When they tried to create a DSN using MS ODBC for Oracle they received an warning to that Oracle Client and Networking component were not found.

Thank in advance!
