I have an ASP.NET application with the following settings:

IIS:
Anonymous access OFF
Integrated Windows authentication ON

Web.config
<identity impersonate="true"/>

When I try to access a file on a network share using:

FileStream fileStream = new FileStream( path, FileMode.Open,
FileAccess.Read );

I can access the file with no problem when I run the application in
the Visual
Studio IDE on my PC or when I access the web application directly from
Internet Explorer on my PC.

When I log onto another PC, access the site and try to access the
file, a network login dialog pops up (this does not happen when I run
on my PC). Completing the dialog box has no effect (it keeps popping
up) and when I click Cancel on the dialog box I get a
Systems.UnauthorizedAccessException. The settings for IE are the same
on both machines

I have verified that IPrincipal in System.Web.HttpContext.Current.User
is the same in both cases.

Any thoughts would be greatly appreciated.
