The list of available shared network resources collected and distributed by the Computer Browser service on a Microsoft Windows NT or Windows 2000 network.
The browse list contains all available domains and servers on the network. This list is distributed to clients who try to connect to shared resources on the network so that they can locate and connect to these resources.
Essentially, when you are using Network Neighborhood, you are looking at the browse list for your network. The browse list is maintained by the master browser computer, but clients that need it obtain it from backup browsers on the network.
If a server or domain is not heard from by the master browser after three announcement periods (amounting to approximately 45 minutes), the server or domain is removed from the browse list.
