SYMPTOMS
When you create a cache rule in Microsoft Internet Security and Acceleration (ISA) Server 2004, the Background Intelligent Transfer Service (BITS) option is incorrectly available for any non-Microsoft Update cache rule that you create.



RESOLUTION
To resolve this problem, obtain the update for HTTP issues in Internet Security and Acceleration Server 2004 with Service Pack 2 (SP2). For more information about this update, click the following article number to view the article in the Microsoft Knowledge Base:

916106 Update for HTTP issues in Internet Security and Acceleration Server 2004 with Service Pack 2



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
The cost of maintaining configuration settings related to the Background Intelligent Transfer Service (BITS) in the stored ISA Server 2004 configuration increases with the number of sites. However, the benefit from using BITS is generally limited to just a few well-defined sites. Therefore, to provide a good user experience with the use of BITS caching, the Enable caching of content received through the Background Intelligent Transfer Service (BITS)option is disabled after you install the update that is mentioned in the Resolution section. After you install the update, this option is only enabled for the Microsoft Update cache rule. However, ISA Server 2004 continues to support BITS caching for Microsoft Update content.

Note You can enable or disable the Enable caching of content received through the Background Intelligent Transfer Service (BITS)option programmatically for any cache rule. You can do this through the VendorParametersSets property of the FPCCacheRule COM object for a cache rule.
