accessing asp.net app on client

I keep getting this "the request failed with http status 401: Unauthorized." error when i access the web app from a client machine.
my configuration:
client - client1
asp.net app - dev1
rs server/db - dev2
sql db - dev3
i'm using nt authentication
the following vb.net code is used for creditentials
rs.Credentials = System.Net.CredentialCache.DefaultCredentials
and yes i do have impersonate = true
however, i do have aIf you impersonate client in you Web App you are hitting the limitation of
NT authentications. NTLM impersonation only survives one machine hop.
client->dev1 is OK, however dev1->dev2 is not possible after that. You need
to enable Kerberos delegations for this.
If you are not impersonating client in your web app, you need to run your
web app under account, known to machine dev2, such as domain account and
give that account rights to report server.
