I am having two shape files: one with houses and one with roads. I am trying to calculate the distances from one point of my houses.shp to all others points, through the road network. I have tried with network analyst but with no effect!! I have also tried the point distance tool, but it calculates an euclidean distance. I' m trying to make it with a python script, but i am amateur in arcgis scripting so any helo would be helpful. Please if anyone knows something about my problem i'm glad to hear a solution about it!!
