How do I remote join Windows 7 to Windows Server 2008 R2 Domain

I am trying to successfully join a WIndows 7 and Windows 8.1 computer to a remote Windows Domain Server via VPN. I need help with the best fit VPN setup so that the remote Windows 7 and 8.1 computers are considered on the same network as the Windows Server. The Windows Server has a public and private IP address both with their own Network Interface Adapters.

You can setup a standard VPN to be considered on the local network.

Once the VPN is setup on the server it's relatively easy to join the remote PCs. Easiest way to join is to use the same user name & credentials on the remote machine as an account on the domain.

Here's the setup for Windows 8.

Windows 7 setup
The recommendation is that you establish a VPN connection to your router or firewall. Most business level equipment will support VPN.

Bad things will happen if you have multiple network adapters on a domain controller. All of the server's IP addresses will be in DNS, and clients will try to connect to your public NIC.

1.having your DC with a public access in leaving you open for many issues.
2. Are the remote win 7 and Win 8 computers on a local lan behind a router?

3. If yes to 2 then setup VPN tunneling between both sites this is secure and preferred.

The DC is on the local network you have a switch and a router and the router has an interface pointing to public access.

Just setup VPN in that router

Not recommended making your DC a router.

Once you have tunneling between the sites joining the domain is not a problem
