SSDP flooding issue...

[jimmysands73_2]

One windows based machine floods network randomly over the course of several hours with SSDP packets (seen via wireshark), about 5000 packets every 10 seconds.....is this behavior normal?   I tried to reserach SSDP, and my impulse would be to say malfuntioning NIC.

Thank you

Forgot to mention the machine in question is just a normal windows machine that is used to play .avi files on a projector to kids in a Junior HS.
