Consider the following scenario:
- You use a Windows Server Update Services (WSUS) server to deploy updates to Windows Vista-based or Windows Server 2008-based client computers.
- The client computers are in a domain environment that has a disjoint namespace.
- You enable Background Intelligent Transfer Service (BITS) peer caching on the client computers.
- You install updates on one client computer (client A).
In this scenario, the other client computers cannot install updates from client A.
Note: When this issue occurs, the other client computers install updates from the WSUS server.
