A prototype system for agent-based distributed dynamic services that will be applied to the development of Data Grids for high-energy physics is presented. The agent-based systems we are designing and developing gather, disseminate and coordinate configuration, time-dependent state and other information in the Grid system as a whole.  These systems are being developed as an enabling technology for workflow-management and other forms of end-to-end Grid system monitoring and management. This prototype is being developed in Java and is based on the JINI support for distributed applications.
