I have a single point file of hospital locations in CA, and the ESRI major roads layer for CA. I need to calculate the distance in miles between each hospital and every other hospital in the point file.

I have added both the points and the roads to a simple network data set. I created an OD cost matrix and added the input points as both the Origins and the Destinations and tried to solve.

The result is one short 'line' for each input point, basically single distance of zero miles since the tool seems to only be reading the nearest origin and destination pair.

How do I setup the OD cost matrix to give me distances between all of my points along the road network?
