030375: The default geodatabase "<value>" is not a file geodatabase and cannot be used as the data source for a network analysis layer. "<value>" in the home folder was used instead. This location will not support use by multiple people at the same time.

Description

The project's default geodatabase is not a file geodatabase. Because the sublayer data for a network analysis layer must be in a file geodatabase, the new network analysis layer's sublayer data has been put in an alternate location.

File geodatabases don't support concurrent access by multiple users, so if the project is shared among multiple users, you may encounter file lock errors.

Solution

You can use the network analysis layer as normal, but don't allow multiple users to work with it at the same time.
