platform:
   All servers are windows 2003 R2 64bit
   MOSS2007 - SP1 with all the latest updates including infrastructure update
   SQL 2005 - Fully patched
PKS - December Release

I've been asked by our infrastructure support team to inquire is PKS a UNICAST or MULTICAST stream ?

Unicast = Connections require multiple connections from the same streaming server even when it streams the same content
Multicasting = broadcasts the same copy of the multimedia over the entire network to all clients
