I'm goint to find the nearest points from a shape file (nearest destination) to another shape file (points as buildings center) through the network analyst.
I tried several times to create the network dataset that all street be twoways without any other restriction.
But the problem is when I built the network from the street shape file or geodatabase, all streets treat as oneway. I went through the ESRI help manual in different way.
I could not figure out what is the problem .

If anyone can help me I really appreciate.
