Dartford closed the gap on the play-off pack as goals from Tom Bonner and Jacob Erskine earned victory at Braintree.
Bonner opened the scoring after converting Ryan Hayes' free-kick from inside the box.
Braintree's Brad Quinton brought a fine save from Marcus Bettinelli with a powerful free-kick while, at the other end, Tom Champion fired against a post.
Erskine doubled the visitors' advantage when he neatly headed Hayes' cross into the top corner from 12 yards.
VIEWS FROM THE DRESSING ROOM
Braintree Town manager Alan Devonshire told BBC Essex:
"I thought it was men against boys. We know what they're about but they did a good job on us.
"We got done with two free headers. It was bad defending - as well as we defended on Saturday, that was kids' stuff.
"Maybe a couple of the lads mugged me off, saying they were OK after Saturday's game and I think some of them were struggling.
"They weren't honest with me and that's something I'll look at big time with regard to Saturday-Tuesday games. I'll probably make changes no matter what the scoreline is on the Saturday."
Dartford manager Tony Burman told BBC Radio Kent:
"This is a difficult place to come, I wanted the players to make sure they were right (after the draw at Wrexham) to come here and I thought we deserved to win.
"Braintree came back at us and we were a bit fortunate not to concede a goal.
"A few of them were running on empty with the games we've had so I'm delighted."
