I forgot where we left off with this prior to NAB. My opinion, is that what used to work, got broken in API 2007.1 providing me customers with a less appealing solution. As a recap, Wiretap 1.7 servers are not auto-discovered unless Internal DNS is running, which most places do not have. I have tested the networks and it is fine, multi-cast pings properly, and Wiretap 2007 servers are auto-discovered as expected.
