A late strike from Jonathan Sanchez-Munoz secured victory for Darlington over Kidderminster.
The Quakers' Adam Rundle had the clearest chance of the first half, forcing a smart save from Dean Lyness from long range.
The home side made the vital breakthrough with 10 minutes left as Exodus Geohaghon headed the ball across the box for Sanchez-Munoz to tap in.
Kidderminster could have equalised but substitute Marc Williams headed wide.
VIEWS FROM THE DRESSING ROOM
Darlington manager Mark Cooper told BBC Tees:
"I thought we played well today, I don't think we got any luck in the box, we didn't get the rub of the green, and the way it's been going you're expecting them to go up the other end and score.
"We kept going, we played well and thoroughly deserved to win today.
"We had numerous bits going across the face of goals and I didn't think we were going to get one, but I'm pleased for Jonathan Sanchez-Nunoz, he's had a rough time but he looked today like he has got a little bit of potential."
Kidderminster assistant manager Gary Whild told BBC Hereford & Worcester:
"I just don't think we turned up for some reason and there were too many players below par.
"There were too many performances at around five out of 10 when we need seven or eight out of 10.
"We're disappointed to come up here and end up going away without anything for our efforts."
