Just a couple randoms thoughts...When you're in WIPIPCFG, does the adapter actually show an IP address or is it all zeros? When you do the Release all, does the address reset to all zeros? You might want to try turning off DHCP, temporarily setting a hard-coded address. Reboot, then turn DHCP back on and reboot again. This basically forces Windows to rebind the prototcals to the adapters. Also, are you sure that TCPIP is bound to the adapter (look under the network properties).
