Browser service or Computer Browser Service[1] is a feature of Microsoft Windows to let users easily browse and locate shared resources in neighboring computers. This is done by aggregating the information in a single computer “Browse Master” (or “Master Browser”). All other computers contact this computer for information and display in the Network Neighborhood window.
