Acess is denied

I am calling an excel application from my .aspx page. I am also manipulating the cells programitically. But I get the following error.

System.UnauthorizedAccessException: Access is denied. I am running the application on IIS5. I have tried including the "all permissions" for ASPNET account and IUSR_MachineName account, but am still getting the same error.


I am bnging my head. Pls help.

check your DCOM settings permission for Excel Application...

Office Automation in Server side is not the best solution. ;)
