Passing credential and authentication

Hi,

 I am having the foloowing problem when i try to deploy my web application written in .net 1.1 and running on Windows server 2003.

I have a web application which tries to access a file server to create a folder in the server. All the while I have been running my application in local host and it was working fine. I user identity impersonate='true' and since i have access to the file server, when I user the application, it works fine in the local host.

But when I port over to the web server which is win 2003, I am not able to access the file server even though I manage to run my web application. All the client and servers are connected to the domain.

So how can i pass my credential to the file server from the web server?

Thanks..
