Ethereal Can the windows version capture 802.1Q correctly? 
It tested. 
It seems that the portion of 802.1Q is missing in windows2K. 
The packet is not captured in windows XP. 
With the linux version, it is capturing correctly.

How is it in your environment?

win2K is Japanese and Professional version.
pcap is 2.2. ethereal version 0.9.2.

windows XP is Japanese, Professional version
pcap is 2.3 beta. ethereal is 0.9.2.

linux is Vine Linux 2.1. 
ethereal is 0.9.1.
