Charlie Sheringham made the first and scored the second as Dartford beat Blue Square Bet Premier bottom club Telford.
The visitors took the lead in the 11th minute when Jason Prior latched onto Sheringham's cross to score his first goal of the season from close range.
Sheringham made it 2-0 just four minutes after the break when he found the bottom corner from inside the box.
Already-relegated Telford went close to a reply when James O'Neil struck the post from the edge of the penalty area.
The Bucks, who sealed their return to Blue Square Bet North a week ago, are now without a win in a record 30 Conference games.
Ironically, their last league win came against Dartford, when they won 4-1 at Princes Park back on 9 October.
