Dover Athletic moved a step nearer the Ryman league title with a 4-2 victory over Dartford.
Despite being behind for more than 30 minutes they secured the points thanks to goals from Jon Wallis, Laurence Ball, James Rogers and Ollie Schulz.
Tonbridge, Maidstone and Ramsgate also won. Ramsgate's 3-1 victory over Sutton was their first at home all season.
Ashford Town won the only surviving game involving Kent teams in Ryman North or South.
Dover's win means their home record in the league is nine wins out of nine.
Manager Andy Hessenthaler told BBC Radio Kent: "Don't take anything away from Dartford. They're a really good side. They tried to come and win the game. Not many teams come here and try and win."
Dartford manager Tony Burman added: "I'm not disappointed with the performance. We had a go against the league leaders.
"We tried to play in the right manner and were a bit unfortunate not to be 2-0 up in the first half."
Ramsgate finally won at Southwood for the first time this season. They came from behind to take the three points.
Manager Jim Ward said: "I kept saying be patient and trust the gods. A lot of things have been working against us but 3-1 flattered Sutton."
Maidstone United beat fellow play-off chasers Canvey Island, despite having to release three first team players because of financial constraints during the week.
Meshach Nugent, Ian Selley and Kevin Watson have all departed the club following chairman Paul Bowden-Brown's decision to sell the club.
Former Gillingham and Hull defender Roland Edge scored the only goal with a wind-assisted long distance free-kick.
Manager Alan Walker said: "The boys restricted Canvey to maybe two chances in the whole game and we won it through a cracking free-kick from Roland, straight into the top corner. A very good performance."
Tonbridge's 2-0 win over Harlow puts them fourth in the table. Simon Glover, who was later sent off, and Carl Rook scored the goals.
Manager Tommy Warrilow said: "It's a difficult place to come, with the conditions we are delighted, especially with the clean sheet and I hope we can build on this."
Ashford Town moved into the Ryman South play-off places with a 3-1 win over bottom side Crowborough.
Ross Cable scored four times for Tunbridge Wells in their 7-1 win over Slade Green in the Kent Senior Trophy.
The games involving Ebbsfleet, Welling, Cray, Sittingbourne, Folkestone, Whitstable and Thamesmead were all postponed.
