Are you using impersonation in your application? The app should use the
ASP.NET process account's credentials unless you are impersonating.

If there is confusion, always check the value of
System.Security.Principal.WindowsIdentity.GetCurrent().Name.

It is also possible to impersonate in code or move the file writing code to
a COM+ component running under a different identity, but that probably isn't
needed here.
