From your SQL Server try the following;
Click Start > All Programs > SedonaOffice Server Tools > Open Sedona Office Server Tools

Select SedonaOffice Server Monitor and click Open.

This will display a list of users currently taking up a license in SedonaOffice. You can identify who is who by looking at the User Name column and the Machine Name column.
You can free up all licenses by selecting “Restart” at the bottom of the window. Note: This will kick all users out of SedonaOffice who are currently in.
It is possible for a license to get held if a user closes their connection to the machine instead of exiting the app. The SedonaService [windows service] manages these licenses and will typically free up any "stuck" licenses within 20 minutes.
