Re: Dell M640 Blade 'unable to connect to DHCP server LNK 00

Hi,

Thanks for getting back to me.

So it magically assigned an IP address with DHCP for IPv4! not sure what it was, the network interfaces aren't part of a LAG on the switch. The issue after that was it assigned the IPv4 address it then failed on the IPv6 with 'unable to save the IPv6 network settings SWC0001'. I rebooted the host and now it won't assign an IPv4 address again?

Is there anyway to disable Ipv6? would there be any reason why it assigned an ip address but then on reboot failed to assign one again? 

The network interface is not part of a LAG on the switch, and just seems intermittent on assigning an IPv4 address with DHCP?
