Read-Only Domain Controller (RODC) is an additional domain controller for a domain that hosts read-only partitions of the Active Directory database. An RODC is designed primarily to be deployed in a branch office environment. Branch offices typically have relatively few users, poor physical security, relatively poor network bandwidth to a hub site, and little local IT knowledge.
RODC is primarily aimed at providing additional security on an Active Directory Database for a server that is not physically secured.
