login failed for use null

I have an extended web application to MS CRM 3.0 that is simply trying to
populate some values from the filtered views.
I receive an SQL Exception Login failed for user '(null)'. Reason: Not
associated with a trusted SQL Server connection when accessing from client
machines. I do have "Integrated Security=sspi" in the connection string.
It works fine from the MS CRM Server. It works from my desktop only when I
have remote desktop connection to the MS CRM server and opened the extended
application from there.
Does anyone have a solution to this?
Thanks
