IE5.1 with Juno

I replaced the hard drive in my daughters computer. K6/2-500, 128mb RAM, Win98, IE5.1.
The last install was Juno 4.0 which run ok.
Before she had setup to use IE in conjunction with Juno to surf the web. When we set up and tryed to log on with IE we get the message of incorrect password. Which is correct.
Now I had installed my Atlantic.net at my home when I was loading everything to check the modem. I removed all traces of it, I could find. Could there be somthing I missed, I generally don't bumb around in the registry looking for stuff.
Is there a procedure to configure IE to run with different ISP's?

Thanks for any help.
