File Replication Service
Microsoft® Windows® 2000 Server uses the File Replication service (FRS) to replicate system policies and logon scripts stored in System Volume (SYSVOL). Each domain controller keeps a copy of SYSVOL for network clients to access. FRS can also replicate data for Distributed file system (Dfs), synchronizing the content of each member in a replica set defined by Dfs. FRS can copy and maintain shared files and folders on multiple servers simultaneously. When changes occur, content is synchronized immediately within sites and by schedule between sites.
