Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query
If you have users connecting to a Domain Controller (DC) in an Azure virtual machine (VM) without access to a Site-to-Site (S2S) VPN, you can enable the Remote Desktop Protocol (RDP) on the VM and use a secure RDP connection to access the DC. You can also use the Azure Bastion service, which provides secure and seamless RDP and SSH access to VMs in the virtual network from the Azure portal. Additionally, you can use Azure Active Directory (Azure AD) or Windows Server Active Directory Federated Services (ADFS) for authentication and authorization for users connecting to the DC.
