you can also try these as well
ipconfig /all will show the your IP address, default gateway, subnetmask, MAC address, DNS servers, ect.... (run this also on your Pro box to check known good settings)
ipconfig /release will release the DHCP leased IP address
ipconfig /renew will query the DHCP server in you router for a new IP address
Check the configuration of your router to make sure that it is dishing out DHCP address, other wise you will need to assign a static IP address to you new machine.
