Strange ICMP packets from windows machines

[Juergen Schmidt <ju () ct heise de>]

Hello,

I got two independent reports, about Windows machines sending large ICMP
echo requests. The weird thing about them is, that they seem to contain a
JPEG image with a microsoft logo as payload (fragmented over two packets)

The packet characteristics are: ICMP, Type 0 (echo request), size > 2000
Byte

One report can be found at: http://www.wfu.edu/~steinsj5/work/icmp.html

I haven't seen those packets myself yet.
Has anybody else observed something similar?

thanks in advance, juergen
