This is my scenario.
I have one Windows 2012 R2 as DC hosted by a ESX in datacenter A. This DC has two NICs:
internal: 192.168.40.1
external: 172.82.180.165
This DC has active directory and RRAS enabled.
The second Windows 2012 R2 is hosted in datacenter B. It has one NIC:
external: 172.82.133.19
Connecting to the DC througn VPN, I was able to join the second 2012 Server to the domain. However, I can´t promote it to DC. It says that a DC for that domain could not be contacted.
If I try to ping the DC from the second server, DNS can resolve name properly.
What am I doing wrong or missing? Do I have to setup RRAS on the second server too? It has to have two NICs? Do I have to add static routes?
Any help would be much aprecciated.
Best regards.
