This is a newly-setup VMware ESXi host 6.0 (3029753). All the networking have been configured, and tested able to ping to any other devices on the network. However, with direct vsphere client to the host, browse to configuration > authentication services > active directory; type in the correct ad domain and credentials, the error message - errors in active directory operation popped up.
I re-check and confirm all the ip addressing/dns, are configured correctly. why?
