The tie will take place on Saturday 25th November, with the Hawks travelling to the Vanarama National South side.
The two sides previously met in the FA Trophy in the 2001-02 season, when after a 2-2 draw in the 2nd Round, Harlow were defeated 2-1 at home in the replay.
The winners of the match will pocket £5,000 in prize money and a place in the First Round Proper when the National League sides, the highest step in non-league football, come into the competition.
As a result of this tie, the away league game against Staines Town has been postponed and will be rescheduled.
