Having ground out a result in their game in hand, Steve Cotterill's side are now on 40 points, 5 points clear of third-bottom Coventry City in the Championship.
The scoreline contrasts sharply with Forest's visit to the King Power Stadium in January when they were hammered 4-0 in the FA Cup.
Cotterill can claim that as another sign of progress with his side now unbeaten in three games.
Reaction to follow on Forest Mad.
