Weird Null Packets

["Michael Glenn" <MGlenn () cco state oh us>]

Hi.
 
I'm getting the weirdest packets trickling out of a network segment, and I'm trying to determine if the switch is 
dying, or if Microsoft has struck again (I've been installing some Win7 PCs on that segment).
 
The packets are pretty-much nothing but a slew of zeroes; Wireshark guessed them to be FibreChannel traffic, but no 
such hardware on the segment. I'm attaching an extracted packet capture. 
 
Anyone seen this before?
 
Thanks.
