Network Analyst issues with Facilities and junctions

Question

I???m very new to Network analyst, and have done the tutorials but am having trouble translating that data to the best way to set up my data.  Trying to do multimodal ND for pedestrians and bikes using streets and trails, however the trail access points and the campus buildings are causing an error when I build the network.

This is the message it gives:
SourceName: Trail_Access, ObjectID: 33, Standalone user-defined junction is detected.
SourceName: UNO_Campus_Bldgs, ObjectID: 29, Standalone user-defined junction is detected.

I want to calculate the service area for the campus buildings but obviously this is not the way to do it 🙂  Any ideas about what I need to do to fix this please?

Thanks,
Lisa
