Description
The network dataset could not be opened to create the network analysis layer or the network dataset layer.
Solution
Ensure that the path to the network dataset is valid. If the network dataset is stored on a network share, the user of the process (for example, the ArcGIS Server user) trying to access the network must have appropriate permissions to access the network dataset.
If the network dataset is licensed, confirm that the license to access the network dataset is successfully installed.
