Another quirky windows thing.

A couple of weeks ago my ISP notified me that I need to change DNS numbers.
Well I started,had a question and called them on the long line and we completed the change.
Since then a pop up window appears everytime I boot that asks forISP connection info.
I have to click on the window sometimes as many as 15 times to get rid of it. Maybe 15 different windows.
At first I thought it was a Norton thing but it hasn’t gone away since I upgraded Norton.
Now I think its just something that windows can’t deal with.
How do I get it to stop.

While I’m not sure what the problem is, I am pretty sure that the best way to solve it is to get back on the phone with your ISP. They can almost certainly provide a quicker, more accurate solution than anyone here!
