File Replication Service (FRS)

File Replication Service (FRS) is a Windows component that automatically keeps folders synchronized across multiple servers, such as those used for sharing system files or network information. It ensures that updates made in one location are replicated to others in real-time, maintaining consistency without manual intervention. FRS is commonly used for replicating the Sysvol folder in Active Directory environments, helping to distribute essential policies and scripts across domain controllers efficiently and reliably.
