2 brand new Vostro 270s straight out of the box both have the same problem. (Windows 7 PRO)
These are connected to a wired LAN, the NIC fails to find the dhcp server and get itself an ip address. The network cable & port work fine with any other PC. If I change the properties in the NIC to a static IP address it works fine.
I have tried every Realtek driver I can find, both from DELL and Realtek, no difference.
I have wiped one of the machines and re-installed a fresh copy of Win 7, then the chipset drivers (from the DELL supplied CD) - no difference.
What virus program do you have installed?
