Hello,
I did as suggested, but I still have the error.
First I updated WinPCAP from 4.1.1 to 4.1.3. No difference. Then I checked the type of my Ethernet board - it was fine, a 1 Gbps device (Intel Ethernet Connection I217-V).
I can add that on the VC707, among the 6 leds near the Ehernet jack, the RX led blinks from time to time and the 1000 led is always on.
Any ideas?
Best regards,
mCezar
