  1. Read/write DC = DC1 on Server 2016 STD on Subnet A
  2. Read Only DC = DC2 on Server 2016 STD on Subnet B
  3. Forest Functional Level = Windows2008R2
  4. Domain Functional Level = Windows2008R2
  5. Perimeter Firewall Rules = Permit any traffic bi-directional between DC1 and DC2
  6. Local Windows Firewall Rules on DC2 = Left at default (ON) + permit all traffic from member server RADIUS1
  7. I can login to DC2 using domain credentials just fine
  8. New member server RADIUS1 in Subnet B to be added to AD via djoin.exe
  9. djoin successfully completed on DC1. Object populated in ADUC
  10. djoin successfully completed on RADIUS1. However the member server attributes such as Operating System version etc do not populate under the properties of the computer object in AD. This is also the case following reboot of RADIUS1
  11. Following reboot: NO DOMAIN CREDENTIALS work. Error: There are currently no logon servers available.
  12. Removed RADIUS1 from AD Domain via going to Control Panel > SYSTEM. Rebooted.
  13. Moved the VM (VMWare) to Subnet A. Domain join works flawlessly. Domain logins work flawlessly.

I am in a fix and am contemplating using Wireshark but want to know if anyone has any inputs/experience on this issue ?
