OK, I'm in a bit of a pickle. At one of our remote sites, we have a Windows Server 2012 R2 read-only domain controller that does not sync Domain Admin passwords. Anytime a domain admin tries to log in, it forwards the request to the primary domain controller back at the home office.
In a recent IP address update, the IP address of the machine was transposed. What was supposed to be entered as 192.168.135.2 was entered as 192.168.2.135. The netmask and gateway IP were set right--meaning that the gateway configured is not even on the same subnet as the IP configured. So the RODC is completely offline.
No big problem. I'll just take another machine, give it the IP address of 192.168.2.130, RDP into the RODC and fix the IP blunder. Except when I RDP into the RODC as an admin, I get authentication errors because 1) it does not store the admin passwords and 2) it has no way of forwarding the authentication onto the PDC because it has an invalid gateway configuration.
Anyone know of any way I can log into this RODC and get the IP address changed back to what it should be?
