Today I replaced my router at home (configured to be a DHCP server) and all the sudden my Vista laptop can't get an IP from it. I've tried wired (numerous ports, wireless, and through a switch. All my other clients (WinXP & Win2003) have no problems... some are laptops, some are servers/desktops, and some are virtual machines. However, when I put in a static IP manually, set the gateway & DNS server, all works perfectly. I'm certain it's not the router... maybe a config on the router I'm missing that's special for Vista? I've had the exact same problem within some hotels... where I can't ever obtain an IP from their DHCP servers. I've also made sure I've got the latest NIC drivers (for both the wired port & wireless port). Also made sure the firewall was disabled (OneCare)... and checked the event log...nothing. For the record, this is a Dell Latitude D820 with a Broadcom NexXtreme 57xx Gigabit Controller. Ideas?

It may be worth looking at your services to make sure the DHCP client service is configured to start automatically and is in fact started.

Try out this small tool I wrote to apply the registry fixes. http://www.reviewingit.com/index.php/content/view/61/1/

Found this thread trying to fix this problem and was wondering if you guys may have any other suggestions.I've already:Applied the registry fixesDisabled IPv6Used built-in repairUninstalled and reinstalled the network adapterSet IP address manuallyStill the exact same problem. "Local only" connection. Can't ping anything ("General failure").XP machines work perfecly fine plugged into the same cable.Thanks.j

By default in VISTA Ping packets are blocked. Try the debugging technics that are mentioned at http://blogs.technet.com/teamdhcp/archive/2007/10/26/unable-to-obtain-ip-address-for-vista-machine-steps-to-debug.aspx Thanks
