Hi,

This appears that they may have a different tns file - than your other clients.

this should be called tnsnames.ora - I would copy this from one of the clients that works and substitute this on the other machine.

With oracle you are trying to connect to a named location with the driver - if the named location is not in the tnsnames.ora file then the oracle client does not have the instructions to connec to the database.  Normally you add entries to this file the more different oracle databases you wish to connect to.

Not the solution you were looking for? Getting a personalized solution is easy.
