Everyone on our subnet at work was having an IP address conflict with another computer on the network. It was traced back to my PC running Mandriva Linux host O/S with Windows 2000 Guest O/S running VMWare Player using Bridged Networking. The conflict everyone had was with my wlan0 wireless card MAC address, which did NOT have an IP address. They saw that I had two IP addresses through eth0 registed with DHCP (for the host and guest O/S's) with some corruption on the DHCP server with the MAC address of my wireless card. I basically disabled NdisWrapper and the problem seemed to not recur. Any thoughts?
