00003: Layer's data source is inaccessible

A layer in your map has a broken data link, meaning the map layer's data cannot be displayed.


More information

A data link is the path that identifies the dataset for each map layer. It is specified as part of each layer's properties in ArcMap.

A broken data link means that the layer's data is inaccessible. As map documents are moved, copied, and renamed, data links are frequently broken. But they can be easily repaired.

See Repairing broken data links for more information.
