On a Windows notebook, one of our consultants couldn't connect to his local Oracle database. We deleted the database, then when we try to create a new database using Database Configuration Wizard, the wizard would report the following errors: ORA-24324, ORA-24323 and ORA-28547. Then we remembered that we recently installed software for a USB-based 3G modem, so we plugged in the modem and now Oracle works again! Don't know why at the moment, but we guess that the absence of the new network adapter was confusing Oracle.
Later ߪ it seems that all that is required is to ensure that the modem adapter software is loaded into memory when Windows is restarted (it was originally disabled).
