I’ve tested Beta11 and Beta12 on 14316 and it worked there. The note on the NAT VMSwitch is actually slightly different. Older Windows builds had an option to create a NAT switch directly which was removed in 1511. We are not using that configuratioHave you tried the udpated steps on the Troubleshoot page?
Do you have any other networking software installed? Like VPN software, DNS proxies etc? We are working on a solution to better interact with these in one of the next Betas
Thanks
