@surennaidu that’s strange then and why it’s not working, how can it resolve the AD domain servers then?
The first step of joining a domain, the client goes looking for _ldap._tcp.dc._msdcs.XXX.local -Type SRV to find who the domain controllers are. It actually throws that error in the windows popup on joining the domain saying it can’t find that record.
@emoscardini notes this in Conneting Remote Endpoints with a On-Prem AD - #8 by emoscardini
He notes that this is passed through, but I don’t seem to see that happening?
