Hi guys, Ive just been going through Webmaster Tools and found in html suggestions I have many instances of duplicate titles and descriptions etc. A lot of this is coming from 2 versions of the same URL being indexed. The only difference is one has an uppercase letter in the URL wheras the other one has a lower case letter.

For example the extensions maybe /green-widgets.htm and /Green-widgets.htm being flagged as duplicate.

Would this affect in any way the rankings of a particular page and is there any way of de indexing the incorrect version without affecting the correct version?

I would really appreciate any help on this issue as it is worrying me slightly that I am being penalised for duplicate content.
