Symptoms

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.

Cause

This issue occurs because BITS peer caching cannot perform authentication in a domain environment that has a disjoint namespace.

    LDR

  • Service Pack 1 is integrated into the release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxx version number.

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section.
