The Distributed Data Management Server
The Distributed Data Management (DDM) Server is used by some clients to process Shared Folder and Remote Command requests. Older original clients used the DDM server for Shared Folders. Newer original clients and optimized clients use the File Server for Shared Folders. Original clients use the DDM Server for Remote Command support. Optimized clients use the Remote Command and Distributed Program Call Server for Remote Command support. The following table lists the DDM Server functions used by the different client actions.
