I have a Windwos 2012 R2 Read-Only Domain Controller in a remote site. Although I suppose everything is configured correctly, it keeps thinking that it is on a public network. I have checked the related question Domain Controller thinks its on a Public Network but it did not help me.
- unplugged and reconnected the cable - no success
- restarted NLA service - nosuccess
- disabled IPv6 (and restarted NLA again) - no success
- tried IPCONFIG /RENEW - no success (the ip is fixed anyway)
- rebooted - no success
There are two NICs physically, but one is deactivated. The other has a fixed address 10.0.50.3/24, gateway 10.0.50.1, ip connectivity to the main site is functional. The network 10.0.50.0/24 exists in AD Sites and Services (also when checking this from the RODC itself) and is assigned to the correct site.
Unless I learn yet another idea here, I am close to assuming that thgis is a design flaw of the concept of RODC and that I ought to promote (rather: reinstall the role) that box to a RWDC ...
