Architecture and Back Office GroupWindows Server Update Service - WSUSThere are many components to WSUS, but basically it is a client/server application. The server component is responsible for synchronizing with the Microsoft Update servers, all updating approved to clients on campus, and logging transactions between the clients and the server. The client component is responsible for querying the server to see if there are new updates available, downloading those updates, and installing them on the first Thursday of the month. After Microsoft releases their updated on the second Tuesday of the month. More specifically, a service runs on a server maintained by Information Resources - Back Office Group that automatically synchronizes with the Microsoft Update servers. Updates that are digitally signed by Microsoft are downloaded to a local repository. Once the server has synchronized and downloaded new updates from Microsoft, they are ready to be approved. All updates are approved on the server and at that point are ready for client computers to download. During the day, client computers will poll the server and download the approved updates that are appropriate for them. Once the updates are downloaded, the client computer will automatically install them based on a predetermined schedule. Supported Platforms
