SYMPTOMS
On a Windows Server 2003 R2 Service Pack 2-based computer, ASP.NET 1.1 does not support the registration-free COM interop functionality in the virtual directory.



CAUSE
This problem occurs because of a regression in Windows Server 2003 R2 Service Pack 2 (SP2). Because of this regression, the side-by-side (SxS) assemblies activation context ignores registration-free COM interop settings at the AppDomain level in the virtual directory.

Apply it only to systems that are experiencing this specific problem. This hotfix may receive additional testing.

MORE INFORMATION
Before you install Windows Server 2003 R2 SP2 on the computer, ASP.NET 1.1 uses the XML manifest file to load registration-free COM interop settings at the AppDomain level in the virtual directory. However, after you install the Windows Server 2003 R2 SP2 on the computer, ASP.NET 1.1 only loads registration-free COM interop settings at the process level.
