Dartford recovered from their FA Cup defeat by Bromley with a 2-1 victory at Salisbury in Blue Square Bet South.
After falling behind, Dartford won the game thanks to goals from Jon Wallis and Jacob Erskine.
Manager Tony Burman told BBC Radio Kent: "I feel brilliant. This is a difficult place to come."
Welling stay third after winning 3-2 at Truro with Andy Pugh, Loick Pires and Jamie Day on target, while Dover and Tonbridge both sneaked late victories.
The entire top four won so Welling and Dartford's league positions are unchanged.
Dartford are fourth, seven points behind leaders Woking with a game in hand, and Burman felt there was never going to be a hangover from last week's cup exit.
I'm delighted for the players to get three points from a difficult place
Dartford manager Tony Burman
"I felt last week we played well enough to win the game," he added.
"If you lose, people think you're terrible and think you're great if you win, but we don't change really.
"I'm told Salisbury have lost four times in about 60 games here, so I'm delighted for the players to get three points from a difficult place."
Dover Athletic left it late to beat Weston-super-Mare 1-0 as Barry Cogan grabbed the winner in stoppage time. It leaves the Whites seventh in Blue Square Bet South.
Tonbridge's recovery came even later as they scored two late goals to beat bottom side Thurrock 3-2.
Without 13-goal top-scorer Frannie Collin through injury, Tonbridge went behind early on but Danny Walder levelled from the penalty spot on 21 minutes.
After going behind again Walder then hit the bar with another penalty before Scott Kinch and Michael Boateng, on loan from Bristol Rovers, netted to give the Angels three points.
Tonbridge manager Tommy Warrilow said: "We made hard work of it yet again. We weren't at our best but we kept chipping away and got two goals late.
"We seemed panicky on the ball. It wasn't one of our best performances."
Elsewhere, Folkestone Invicta and Thamesmead Town won FA Trophy ties against Daventry Town and Arlesey respectively.
Maidstone kept the pressure on Ryman South leaders Dulwich with a 3-1 win at Eastbourne and, after a 6-6 draw in the first leg of their Kent League Cup tie last week, the goals continues in the second leg, as Fisher beat Canterbury City 5-2 to win 11-8 on aggregate.
