automation "Object reference not set to an instance of an object."

[Guest]

I'm doing a server side automation(I know it's bad but..) and its working
fine locally and when accessing it from a remote machine using web browser is
was giving me this error"Retrieving the COM class factory for component with
CLSID
{000209FF-0000-0000-C000-000000000046} failed due to the following error:
80070005". so I configured the server using dcomcnfg as described in this
link:
http://support.microsoft.com/kb/288368/
and know this error now is gone but I'm having this error:"Object reference
not set to an instance of an object." when it comes to the last line of this
code:

Word.Application wrdApp;
Word._Document wrdDoc;
wrdApp = new Word.Application();
wrdDoc = wrdApp.Documents.Add(ref oName, ref oFalse,
ref oMissing, ref oMissing);
wrdDoc.Select();

Do you actually have a valid object? meaning is wrdApp non-null? If this is
true, the particular property or method may not exist on the object.

But, why it runs OK when I run it in local machine in the debug mode!?

The probable explanation for this is that you have two different word
objects installed on these different machines. You can go trouble-shooting
to find out, but it's really an exercise in futility. Just make sure that
the app that is failing contains the appropriate word version registered.
That may clear it up.
