Hi: We encounter this problems at beginning of WinPcap 3.0 alpha test. It never go fix. Using gigabit NIC card will cause memory corruptions in WinPcap drivers. Some one need to debug problems out.

I have a problem while using PacketSendPackets function on gigabit ethernet. About 30% of packets have a broken content. I wrote test programs, sender and receiver, and made some tests. My configuration is: 1-st computer (sender): Windows 2000 Pro, 2G RAM, Intel PRO/1000 MT 2-nd computer (receiver): Windows 2000 Pro, 512M RAM, Intel PRO/1000 MT WinPcap ver. 3.0 Comparing files original and received1 00000410: FE 00 00000411: FF A0 00000412: 00 6F 00000413: 01 88 Comparing files original and received2 00000221: 10 00 00000222: 11 A0 00000223: 12 6F 00000224: 13 88 Comparing files original and received3 00000031: 22 00 00000032: 23 A0 00000033: 24 6F 00000034: 25 88 Looks like driver (winpcap?) replace some user data in buffer by integer value. This value is the same for all broken packets. I'm ready to give source code of this test's on request to [EMAIL PROTECTED] Also, I have problem whits PacketSetBuff function. On 512M RAM computer PacketSetBuff allow to set up to 12Mbyte buffer size, while on 2024M RAM computer PacketSetBuff NOT allow to set more then ~1Mbyte buffer. P.S. Sorry for my English, it is not my native language. ================================================================== This is the WinPcap users list.
