Dagenham & Redbridge suffered a 10th league defeat of the season as Barry Fuller scored the only goal of the game to hand AFC Wimbledon the three points.
Wayne Burnett's side had opportunities to level in the first and second half but failed to take them.
And in the end, it was another encouraging display that brought no points.
The Dons started strongly with Dannie Bulman having a shot deflected wide before Adebayo Akinfenwa had a header cleared off the line by Ashley Hemmings
And in the 19th minute they took the lead through full back Fuller.
George Francomb's corner was met by Adam Barratt and his knock down fell perfectly for Fuller, who lashed past Mark Cousins
from close range.
Daggers regrouped, though, and George Porter
failed to test James Shea on two occasions before he nearly created the opener for captain Abu Ogogo
Porter cut inside his marker and chipped perfectly in the box but Ogogo side footed wide.
Four minutes before the break Ashley Chambers
had a volley deflected over the bar as the Victoria Road outfit ended the half strongly.
Neither side threatened too much at the start of the second period but the introduction of Rhys Murphy
and Jamie Cureton
gave Daggers great impetus.
Murphy immediately flashed a ball across the face of goal before Cureton was brought down outside the box.
The resulting free kick failed to fashion an opportunity but Daggers were furious 15 minutes from time.
Chambers passed into Cureton and although he missed his effort, with Dons keeper Shea close, he was brought down by the home keeper inside the box.
However, much to the astonishment of everyone inside the stadium no penalty was awarded but it didn't stop the visitors.
A minute later Ogogo put Chambers one on one with Shea but he side footed wide.
Burnett sent on recent recruit Ayo Obileye late on but he couldn't change the course of the match and Daggers suffered another league loss.
