I was having the GEN_FAILURE code 0x0000001f problem too, so I skeptically installed SMB1, and it worked! I'm a little perplexed, though. Why does something as modern as ESXi require SMB1 to function properly in an AD environment? SMB1 has serious security issues - a vulnerability found in it was the exploitation responsible for the WannaCry virus that took down huge swaths of the UK health ministry, etc. so needless to say, I usually turn it off. edit: I found a reddit thread with instructions on how to enable SMB2 in ESXi and VCSA: https://www.reddit.com/r/vmware/comments/6biy08/wannacry_smb1_and_vsphere_products/
