When you run the Distribution Service, messages are not sent, and the following error is logged to the Diagnostics Console: Workstation Registration not found for distribution server machine.
This error is displayed because required OnBase components such as registry keys and the onbase32.ini file have not been created on the server running the Distribution Service.
To resolve this issue, log in to either the OnBase Client or the OnBase Configuration module from the server that is running the Distribution.
