Here is some more info regarding the port sweeps.  The port the client
is being hit on seems to vary.  The client is being hit on the same 8
port range from each IP port 33434-33460.  All 3 sensors from the 3
different clients show the same destination port range.  The sensors are
cisco IDS sensors and I am unsure as to how to get the actual packet
from the event.

That port range smells like traceroutes. I've seen a lot of that kind of traffic to nameservers, mail servers and HTTP proxies. It often originates from load balancing DNS systems and other such things.
