I've tried it on an IBM Client for e-business build of XP with all the 
required patches. This build has ZoneLabs Integrity Desktop and does not 
have SP2. Ethereal is 0.10.11. WinDump 3.8.3 beta. WinPcap 3.1 beta 4.

Using the built-in Intel PRO/1000 (driver Intel 8.0.57.0) I got the same 
result as Harry with each of Ethereal and WinDump, with and without 
ZoneLabs running. Each sent ICMP packet is duplicated after roughly 
0.0004 to 0.0005 seconds.

I also tried a Xircom CardBus Ethernet 10/100 Adapter (driver Microsoft 
3.14.5.0) in the same laptop. This did not duplicate the sent packets.
