Hi,
We have a main office in London, UK. And a remote site in Asia with a read-only domain controller. This RODC is an authorized DHCP server for a scope which is unique to the Asia office.
This past weekend their internet connection went down for 72 hours, from Friday night until Monday night. Shortly after it went down, the RODC started logging Event 1059 "The DHCP service failed to see a directory server for authentication". Unsurprising. It also stopped responding to clients on the network.
This caused havoc with the clients as when they booted up on Monday morning, DHCP was not running so they all received a 169.x.x.x address.
My question is if a RODC could not reach another AD server, how long is it before the DHCP service on RODC stops?
And would having a RWDC in that office overcome this issue?
Thanks in advance.
