In the Open Dental install folder, run CentralManager.exe.

The Central Enterprise Management Tool (CEMT) allows Multiple Locations to use separate databases at each location, yet have a centrally located management tool to interact with all the databases.
The CentralManager.exe is installed in the same Open Dental folder as the main program. It connects to a mostly blank Open Dental database (e.g., dbcentral) that does not have any patient information or use most of the normal tables. It does have some of its own tables that are ignored by the ordinary Open Dental program.
From this central location, easily:
- Launch database connections.
- Search for patients across multiple databases.
- Set up database connections.
- Check the database connection status and version in contrast to CEMT database version (upper left).
- Configure and sync security settings.
- Run a production and income report for multiple databases at once.
Requirements:
- All offices need to be on a single VPN.
- If using the Middle Tier at each location for increased security, connect over the VPN or over https.
- If using one-way Replication, the CEMT tool should only connect to a local copy of the database, not the remote databases.

Troubleshooting
Problem: Name conflicts when syncing users (states which names are in conflict).
Solution: Rename the CEMT user using a unique username. For example, Open Dental user Sally, could use SallyCEMT as her CEMT username. The chances of conflicts are very slim. After renaming users, make sure to sync all Open Dental databases.
Problem: Log in failed message when trying to connect to an Open Dental database.
Solution: Sync the CEMT credentials for the user to the Open Dental database.
Problem: SERVER OFFLINE: incorrect username or password on a middle tier connection.
Solution: Ensure that the user currently signed into CEMT has a password set.
Solution: Ensure that the username and password exist in the database connection. If unable to push the credentials for the user from the Central Manager, the CEMT connection can instead be changed to a direct connection to try to push the users through.
Problem: CEMT stopped working after an update, and the version is in red font.
Solution:
Update CEMT to the version of the database (or higher).
Problem: CEMT windows resize themselves when clicking in a grid or some text is cut off in the CEMT interface.
Solution: Override high DPI scaling behavior in Windows for CentralManager.exe (not for OpenDental.exe). See
Zoom, Turn Off DPI Awareness, Option 2 for instructions.
