Hyper-V - RRAS - 2 forests With different Subnets RRS feed

  • Question

  • Hello all,

    I'd like to connect 2 DC's in my Hyper-V

    DC1 - IP : 192.168.1.1 - Subnet Mask : 255.255.255.0 - DNS : 127.0.0.1 - AD DS Installed/DNS service

    DC2 - IP : 192.168.2.1 - Subnet Mask : 255.255.255.0 - DNS : 127.0.0.1 - AD DS Installed/DNS service

    Both are using the Local Area Network - Virtual Adapter.

    My question is, how can I make my DC's see each other ?

    I saw that a RRAS could help to do that, but have no idea how to set it up.

    I Have a third VM with Windows 2008 R2, and followed a step-by-step RRAS installation, but from here, I have no idea how to continue the configuration.

    Thanks for your help.

  • Hello,

    first of all this is frensh forum and not an english forum.

    DC1 - IP : 192.168.1.1 - Subnet Mask : 255.255.255.0 - DNS : 127.0.0.1 - AD DS Installed/DNS service

    DC2 - IP : 192.168.2.1 - Subnet Mask : 255.255.255.0 - DNS : 127.0.0.1 - AD DS Installed/DNS service

    That is not recommended.

    I suppose here that each DC is for a domain in a forest. So, please make each DC points to its private IP address as primary DNS server and to 127.0.0.1 as secondary DNS server. Once done, run ipconfig /registerdns and restart netlogon on each DC.

    My question is, how can I make my DC's see each other ?

    You have to configure a trust relationship between between both domains if you want to access resources of other domains.

    For that, you have to make sure that both domains have not:

    • The same SID
    • The same domain name
    • The same NetBIOS name

    Once done, you can create conditional forwarders and create the wanted trust relationship (Unidirectional or Bidirectional).

    I saw that a RRAS could help to do that, but have no idea how to set it up.

    Avoid enabling it on DCs as it is not recommended.

    As you are using Hyper-V, you have two choices:

    1. Put them in the same network and let them use the same subnet
    2. Add a VM and install RRAS on it. Once done, configure routing between your subnets

    I Have a third VM with Windows 2008 R2, and followed a step-by-step RRAS installation, but from here, I have no idea how to continue the configuration.

  • Bonjour,

    Malheureusement, l'anglais étant de base, je n'ai pas fais attention à ca.

    Merci, la prochaine fois j'écrirai directement en Français :)

    Bonne journée.
