It should be where you sign in on yahoo. where you paid for the domain.

yeah but yahoo discontinued my service because they want me to pay them 34 usd for renew my domain so i can not access the capanel to make the changes and transfer the domain to the new hosting server> any other input?
thanks

you dont go to cpanel. go to yahoo where u bought the domain.

Is this where you first went when you got it?
