Cannot complete [UnRegister] operation because of failure to start or connect to repository <repository_name>.
The Repository Service could not unregister a local repository from a global repository because it could not start the Repository Agent process for one of the repositories.
Check preceding error messages in the Repository Service log file to see the cause of the error. Verify that the repository database is running. Verify that the repository configuration information is correct. Verify that another Repository Service is not running a Repository Agent for the repository.
