I found this when trying to figure out why my dual-boot win7 and ubuntu 10.10 machine kept failing to acquire DHCP from my router.
http://forums.fedoraforum.org/showthread.php?t=240880 Scroll down to post #3 to get the fix he used. Here is a brief on it. Basically the person had the same issues I had. Dual booting win7 and Linux (most likely any distro), and almost randomly switching between the two OS's would cause a DHCP failure in usually the linux install but less frequently the Win7 install. The firmware is all there, the drivers, et al. The NIC (s) would be recognized and functioning, but it would fail to register itself with a DNS lookup with a DHCP server. He found 2 issues . >From the post: "I've managed to sort the problem after a bit of playing with both Linux and the CentOS server. For anyone looking for a solution to the same problem, it was down to two separate faults: 1) The Linux installations (both Ubuntu 9.10 and Fedora 12) needed to have the "DHCP client ID" field set to the NICs MAC address - this is within the eth0 IPv4 panel of Network Manager. This allows the DHCP clients to appear to be as the same machine to the server, as Windows sends this DHCP "uuid" to the server by default. 2) There was also a mis-configuration of the DNS zone files, with the trailing dot being left off on the reverse lookup zone, so it might have been unrelated but it could have contributed to the overall not-working- ness of the server. After refreshing the DHCP lease caches on both the server and the clients, all three OSes on the PC are now assigned the same IP. This problem can really only occur on machines multi-booting, but it could be useful nonetheless Thanks " I have been using this with no issues for two days now.
