Peer Caching Cache

Applies To: Windows Server 2008

The following is a list of all aspects that are part of this managed entity:

Name Description

Cache Integrity

In order for BITS to download content from a peer server, data in the peer cache on that server must not be corrupted. If data in the peer cache is corrupted and BITS encounters an error while reading the peer cache, BITS will attempt to delete the cache, and then recreate the cache to handle future requests. If this attempt is not successful, the cache might have to be manually cleared.


In order for BITS to cache downloaded content, peer caching must be enabled for the  BITS peer caching server by a domain administrator.
