Built up a trust between 2 Azure DCs

Question

Hi,

i've got two DCs and I want to setup a trust.
Both DCs are Azure VMs (different Subscription).
Can somebody please tell me which configurations i have to do.?
Because I followed the official Microsoft kb and it didn't work, maybe because of the Azure based VMs

Answer 1

Hi

You can use Azure vNet peering across different subscriptions and tenants to join virtual networks together. Once you set that you you will be able to communicate between the different VMs.

https://azure.microsoft.com/en-in/updates/cross-aad-vnet-peering/

https://learn.microsoft.com/en-us/azure/virtual-network/create-peering-different-subscriptions#cli

Once you establish the Peering between 2 VMS(Different subscriptions) you can establish the trust between 2 different Azure DC VMS

Please follow the ==> https://azure.microsoft.com/en-in/resources/templates/active-directory-new-domain/ building the DC, once you build please refer ==>https://techcommunity.microsoft.com/t5/azure-compute/trust-relationship-failed-cannot-logon-to-azure-vm-with-domain/m-p/154687
