Push the string to the side on the fret where it's making the noise. Look for a groove in the fret where the string would touch if you played it. If you have a groove there, that's going to make the next fret up cause the noise. It the same noise as having a high fret, but one is lower instead.
If you have a 6-string guitar around look at the second fret under the G string, and you'll probably see what I'm talking about.
1) new fret
2) raise the string a little
3) live with it
4) don't play that note
