Failed to call SSIS package from ASPX C# Web Page

Hi, Everyone:

I am getting the following error message when I try to execute a SSIS package from an asp.net page written in C# 2.0. What I am trying to do is basically just click on a button in the web page and it will execute the package. The code to execute the package is pretty simple. I pass the path of the DTS package stored in the local folder. This works fine in the machine where SQL2005 is installed locally. But it fail when I have a seperate Web Server and SQL Server. Any ideas? Do I have to install SSIS or SQL2005 on a web server as well?

Thanks

static public string Execute_SSIS_DTS(string DTS_Path)

{

Microsoft.SqlServer.Dts.Runtime.Application app;

app = new Microsoft.SqlServer.Dts.Runtime.Application();

Package package = app.LoadPackage(DTS_Path, null);

DTSExecResult result = package.Execute();

return result.ToString();

}

Yes, to use SSIS object model and to execute package you do need to install SSIS on this machine, of course.
