Event ID 101 — Core Functionality

Applies To: Windows Server 2008 R2

In order for a BITS peer caching client to download content from BITS peer caching servers, at least one peer server must be available on the network to serve the content. The client must also be able to receive peer server announcements, to discover available servers. A peer server announces itself after it starts. If more servers are needed for its peer list, the client must be able to broadcast a request for peer servers.
