Vista guest can't reach DHCP server in Bridged mode on 4.1.6

[rgsteele]

Hey all,

I recently upgraded to VirtualBox 4.1.6 (on Ubuntu 10.10 amd64), and now I'm having trouble with my guests running Windows Vista. They are configured with virtual Intel Pro/1000 MT Desktop Ethernet adapters connected to the Bridged Adapter. They seem to be unable to contact the DHCP server, ending up with 169.254 IP addresses. I've tried rebooting both host and guest, to no avail.

Another guest with the same network configuration, but running Windows 7, seems to be working fine.

Anyone else seeing this issue, or have suggestions as to how to troubleshoot?

Update: I discovered I had not yet updated the guest additions on the Windows 7 guest -- it is still running the 4.1.4 guest additions. I suspect my issue may be related to https://www.virtualbox.org/ticket/9860.
