# Test and Troubleshooting

After a successful installation of the client software you will be able to start the ZeeBORN software via the icon on the Windows Desktop. After installing the system for the first time only the Administrator account with password "admin" will be available for log in. As the database usually doesn't contain any further data at this point, you'll only see a message informing you about the missing data in the system. If you reach this point, everything is properly installed and ready to use.

# Solving database access error

There are several potential problems you might have to solve if the software isn't starting as expected.

1. Firewall Settings: Please make sure that the firewall on the server allows communication through port 3306 (or the port defined during database engine installation). Usually the required settings are automatically added while installing the database engine. If you use another firewall solution than the one coming with Windows/Windows Server, you will need to open the port manually in your firewall.
2. License Problems: If you encounter licensing problems after successfully activating a license, please make sure that the name of the server is identical on all connected clients. If for some reason only the IP address of the server can be used or a fully qualified domain name (like server.domain.local), make sure that all connected clients use the same name. Using different names for accessing the same server will invalidate the license.

# Solving database performance problems

There are several aspects to be checked for ensuring a good performance of the database server.

1. Do not use VPN or other WAN connections between client and server. The software is optimized for being used in a local area network with direct access between server and client.
2. Set the Power Options on the server to High Performance
3. Do not use the compression option provided by Windows for the data folders.
4. Consider upgrading the data disks to a solid-state drive (SSD)
