The creation of duplicate workstation registrations has been known to occur when upgrading from OnBase 8.0.0 or earlier. In OnBase 8.0.0 and earlier, the registernum key in the registry was referenced by OnBase to identify a unique workstation in the database.
Starting with OnBase version 9.0, the machineid is used to identify a new (or existing) workstation. The machineid is a unique number that is generated using Windows Management Instrumentation from 14 different machine characteristics.
Because of the change in methodology for determining a unique workstation ID, you may experience duplicate workstation registrations after an OnBase upgrade. If this occurs, contact your first line of support for assistance.
