User Profiles Being Renamed To Include Computer Name

I recently had to do a system recovery on WinXP, and when it was complete, it had renamed all my user profiles to: [USERNAME].[Computer Name] rather than just username.IE: C:Docume~1JohnDoe.My_Computer instead of C:Docume~1JohnDoe
Unfortunately, all my settings, documents, financial files, etc are located under the original JohnDoe folder (still present).How can I redirect the JohnDoe log-in to look at the JohnDoe folder rather than JohnDoe.My_Computer?(side note, I set up my computer to share, and when I put in the computer name, I spelled it slightly different than the original. I have changed it back to the original spelling, but with no success. I have also deleted the new folder, just to have it recreated at log in!)
