Martin,
Thanks for the reply. I came across what I believe the
problem is. Apparently if MSN Messenger is running
even with SSDP / UPNP disabled messenger will try to
send SSDP / UPNP traffic to find services. I'm going
to check on this tomorrow. Theres a registry tweak to
turn off the SSDP / UPNP stuff that MSN uses or just
not use Messenger.
But still curious why a L3 routing switch sends
hundreds of ICMP redirects to this client after just 1
SSDP / UPNP packet. One or two would be
understandable...
