Forest Green's play-off hopes took a knock and Northwich still have relegation trouble after they shared the points and both ended with 10 men.
David Brown put the home side ahead when he poked home from 12 yards after good work on the left by Lee Steele.
Daniel Carey-Bertram levelled for the visitors early in the second half when he turned home Anthony Tonkin's cross.
Michael Byrne was booked twice in three minutes late on and Tonkin followed him off in injury time for two bookings.
