On a Windows-based server that is running Windows Internet Explorer, you install an Internet Explorer cumulative security update that is greater than MS07-045 (KB937143). In this case, when you use any web browser to browse that server, you receive the following error message:
object error ‘ASP 0177 : 8000ffff’
<FileName>.asp, line <LineNumber>
This problem occurs if a website that you browse is an Active Server Pages (ASP) page that calls a .NET-managed component.
Note This .NET-managed component uses .NET interop functionality.
