Problem automating word on IIS

Hi experts,

Scenario / Goal

I am writing an Intranet system that uses data on an sql server. The web application needs to be able to 'mail merge' MS Word templates with some basic client details.

I am using Visual Studio 2008 and within that environment the application works fine; It launches Word and can do the merge. When I try to deploy to my Internal webserver the app crashes with the following output:

Server Error in '/Beta' Application.

Word could not fire the event.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Runtime.InteropServices.COMException: Word could not fire the event.

Source Error:

Line 21:         oWord = CreateObject("Word.Application")
Line 22:         oWord.Visible = True
Line 23:         oDoc = oWord.Documents.Add("c:\temp\standard letter.dot")
Line 24:        
Line 25:        

Source File: C:\Inetpub\wwwroot\Beta\Word Automation.aspx    Line: 23

Stack Trace:

[COMException (0x800a1772): Word could not fire the event.]
   Microsoft.Office.Interop.Word.Documents.Add(Object& Template, Object& NewTemplate, Object& DocumentType, Object& Visible) +0

   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +36

Version Information: Microsoft .NET Framework Version:2.0.50727.3053; ASP.NET Version:2.0.50727.3053

Environment / History

I am using an XP Pro (SP2) machine as the webserver
Running IIS 5.1
I have word 2003 installed on the server
I have installed the MS Office 2003 interop on the server
My test aspx page is attached. It displays the current user and that user is displaying as ASPNET when I run it on the server.

On the server I have done the following to try to resolve the situation -

DCOMCNFG.exe / Found the component (Microsoft Word Document)
Properties / security tab / added ASPNET user to customise settings in launch/access/config
Identity tab is set to 'The launching user'
This changed an initial error message of 'Exception Details: System.Exception: Cannot create ActiveX component.' to the following error where it cannot fire the event.

Any thoughts?
