From Microsoft's support page "Considerations for server-side Automation of Office":

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.

The above article also specifically names the error you encountered as being among those which are likely to occur when trying to use Automation in a server-side application.

Excel Automation really shouldn't be used in a web application at all. The current recommendation is to use the OpenXML SDK instead.
