Read Only Domain Controller (RODC) - I thought the purpose was for a remote location to be able to handle logons and other Active Directory stuff instead of having to constantly communicate with the primary location. Based on this understanding, I built an RODC at my work location for the domain running at my home, in theory this would make things smoother with my (home) domain connected Surface Pro devices when I carry them to work. There is a VPN connection between the two networks. In real-world practice, however, my home Internet was down this morning. I had all kinds of problems doing things that normally work. I could not even login directly on the RODC because "no logon servers are available" - all resolved itself when the home Internet, and therefore the VPN, came back online. What exactly is the point of an RODC, if it is supposed to handle such a situation then obviously I have something configured wrong. Where to start looking?
yea its look something about the configuration maybe its still connect to DC and not the RODC maybe in services and sites need to be configured
