Managerless Barnet scored three goals in six second-half minutes to secure a fine comeback victory at Bradford.
Luke Oliver headed in a David Syers cross to put the home side ahead, and fellow defender Shane Duff also hit the post with a close-range effort.
But the Bees equalised on 61 minutes when Rob Kiernan headed into his own net and Anwar Uddin nodded in a Glen Southam corner to put Barnet in front.
And Izale McLeod then teed up Rocky Holmes who tapped home to seal the win.
Bradford City manager Peter Taylor tells BBC Radio Leeds: "I thought we were going to do better. We didn't play particularly well in the first half, not so sure we deserved to be 1-0 up at half time, but we'll take that.
"Then the second-half with a little bit of luck we could have gone two ahead and I think then we would have had a better afternoon.
"Then all of a sudden we conceded two of the easiest goals you can concede and we've then made it a bit easier for Barnet."
Barnet caretaker manager Paul Fairclough told BBC London 94.9: "It was a terrific response. We didn't have much time to do much work with the lads before Stevenage.
In the position we're in we need warriors. I knew the eleven players I was putting out on the pitch today would show the kind of desire that the fans expect.
"It's been a bit of a culture shock for the players, they've been in twice a day for the last five or six days but they've got their reward today."
