We have a cross site VPN to Azure. I have set up a VM in Azure to be a domain controller & DNS. I then added this machine as a DNS in my Azure Network.
Afterwards I joined a local machine to the new domain, it took a very long time, but eventually joined it. (Not sure why, because we have a very fast connection between our office and Azure). Then I attempted to join this server as a secondary domain controller, it failed. It would not get past the screen where it asks for credentials to for the domain. It keeps coming back, (after about 10 minutes), that the credentials supplied is invalid.
I give up at this point, can anyone please help.
Thanks.
