So I am switching a client from dsl to cable and we are switching to dhcp IP's from a linsys besfr41 Cable/Dsl Router switch. I can obtain an IP from the router for the laptop but not on the desktop unit. When I run ipconfig /release it says its already done and when I run ipconfig /renew it errors out and says it can perform the task. I tried to rebuild the tcp/ip stack but I cant remove it in network neighborhood. Any ideas would be greatly appreciated.
