Sorry for the delay, had to deal with another network problem. I performed the tests you suggested and here are the results: I used a crossover cable to link my laptop and my server. The server is equipped with a configured as autoselect. I tried to force the media both 10 and 100 on both card and the only case i had the Broadcom card active was when I set the server NIC to 100. But in that case, the RealTek NIC was not active. Maybe I have to change the NIC on the server :( The other tests I did besides the previous one was to boot in Safe mode and to unload usb. Now, I don't know what to do. Thanks for the fix anyway ;) Phil.
