1. **Understanding the Network Configuration Error** The "Network Configuration Error" often appears in Aimsun Next when managing highly complex traffic networks. This issue arises due to improper parameter settings or excessive network detail, which can overwhelm the simulation process and lead to crashes or slow performance.

2. **Simplifying Network Complexity** One effective way to resolve this error is to simplify the network design by focusing on essential roads and pathways. Remove minor or less impactful elements to streamline the network and reduce the load on the system, which can greatly enhance simulation stability.

3. **Adjusting Network Parameters** Double-check your traffic network parameters, such as traffic flow rates and speed limits, to ensure they are set optimally. Fine-tuning these parameters can help maintain a balanced load, preventing the simulation from stalling or causing configuration errors.

4. **Increasing System Resources** For extensive traffic networks, upgrading your system’s resources can significantly improve performance. Ensure your machine meets Aimsun’s recommended specifications, and consider adding more RAM or upgrading your CPU for handling larger simulations effectively.

5. **Updating Aimsun Next Software** Outdated software versions may contain bugs that lead to network configuration issues. Regularly update Aimsun Next to the latest version to take advantage of bug fixes and performance improvements introduced by the developers.

6. **Using Aimsun’s Error Detection Tools** Aimsun Next provides built-in tools for error detection within traffic networks. Utilize these tools to identify configuration problems in your model, and follow the suggested adjustments to resolve potential issues before they impact your simulation.
