Vista DHCP - Lenovo Laptops
Not sure whether to post this in the Vista forum or the hardware forum.
We've bought lots of new Lenovo R61i laptops with Vista Business. We've decided to stick with Vista on these rather than 'downgrade' to XP
They work quite well, but there's a really strange DHCP problem, the likes of which I've never seen before.
If the machine is started up with the Ethernet cable plugged in, 9 times out of 10 it will fail to get an IP address via DHCP. The network connection icon in the system tray just says "identifying" and ipconfig /renew at the command prompt hangs for ever. If you go into the network connections dialog and change anything, it just hangs forever after clicking OK.
If the machine is started up without the Ethernet cable plugged in, and is then plugged in after it has started, it gets an IP address immediately, every time without fail.
This is really annoying as it means that group policies don't get applied without lots of reboots and logins fail most of the time. We've tried new LAN drivers (Broadcom NetLink) from both the Broadcom and Lenovo sites - different driver versions, but result in the same behaviour. We've tried Vista with and without SP1, no difference. We've updated the BIOS to the latest version as well.
Has anyone seen anything like this before? Is it a Vista thing or a driver problem as I suspect? Other latpops (HP) with the same Vista configuration have no problems at all. DHCP server is Windows 2000 with no routing or DHCP relay.
