Halifax secured their first home win of the season as they became only the second team this season to beat high-flying Dagenham & Redbridge.
Jake Wright put the Shaymen ahead with a 20-yard effort three minutes before half-time, then Ryan Sugden converted Danny Forrest's cross.
The Daggers reduced the deficit on 53 minutes with a David Rainford penalty.
But Forrest broke into the penalty area and clipped a superb shot inside the far post to complete the victory.
