ACTIVATING PASSWORD SAVING IN DIALUP

I HAVE CONFIGURED A PC RUNNING WINDOWS 98 FOR DIAL-UP TO THE ISP USING THE ATTACHED ROBOTICS MODEM.
THE MODEM DIALS OK AND ESTABLISH CONNECTIONS AS OFTEN AS NECESSARY. BUT THE PROBLEM IS THAT THE “SAVE PASSWORD” DIALOGUE BOX IS GREYED OUT EACH TIMETHERE IS NEED TO DIAL AND SO WE KEEP TYPING IN THE PASSWORD FOR AS OFTEN AS IT TAKES TO ESTABILSH A CONNECTION INSTEAD OF THE PASSWORD BEING SAVED AND THE USER JUST NEEDING TO CLICK RETRY WITHOUT TYPING IN THE PASSWORD REPEATEDLY.
WHAT COULD BE WRONG AND HOW CAN IT BE CORRECTED.
THANK YOU.
