I just installed/upgraded a Dell with XP Pro SP2 to the release of Vista Business. I am a Volume License Customer and Microsoft pre-released it to us a few days ago. Here is the problem, which by the way I experienced on a differerent system with an earlier beta or release candidate. I chalked it up to being a beta, and went back to XP. Now I upgraded a system to Vista Busiess, and when I had the same proiblem I blew away the system and installed the full version of Vista only to have the same problem.
The problem is I can't get an IP address. Vista comes out of the box with both IPv4 and IPv6 selected. I run a Win2k3 server hosting IPv4 DHCP and it works fine for any other device in my lab. The workstation says it has limited connectivity because it won't get an IP from DHCP. I have deslected the IPv6 option and am using ver 4 only. When I look at the server, the DHCP IP list shows constant BAD_ADDRESS in it, which are coming directly from the Vista PC. Each one of those BAD_ADDRESS listed in DHCP have a unique identifier to diffrentiate it from the initial mac address. I have even gone into the properties of my nic and changed its mac address, still no luck. When I look at the logs of the workstation and server, it is complaining about a duplicate IP address and then DHCP tries to deliver another address and it just keeps going on and on. I have Googled this problem to no avail, asked all my tech buds and no one has a clue. If this is what we can expect out of a commercially released product in Vista, I'll still with XP or the gretest OS ever built Windows 2000. I also have tried just statically assigning IP info and an IPCONFIG shows that no matter what address I assign to the NIC it shows up as a duplicate. Racking my brains for a few days now and no luck, any help would be greatly appreciated.
