Hi William, I couldn't quite tell what the problem was that you were experiencing. What adde server were you trying to connect to? Have you had success in the past connecting? It might be a firewall issue. We connect to adde servers on different ports. Please see the response: http://my.unidata.ucar.edu/content/support/help/MailArchives/idv/msg00483.html Jeff
