A. The File Replication Service (FRS) is Windows 2000's answer to the old LMREPL service from NT 3.x and 4.0 and is far more powerful in scope with its multi-master replication engine.
A replication cycle is triggered once the NTFS change log detects a file in the DFS or SYSVOL tree has been closed. 3 seconds is given before the replication is started as an aging cache so that only the last iteration of a file being rapidly changed is copied.
The following files/folders are not replicated:
- Folders that are outside of FRS. FRS replicates files and folders in SYSVOL by default. The contents of DFS fault-tolerant roots and child replica members are replicated when replication has been enabled in Dfsgui.msc and each level of the namespace is "backed" by more than one Windows 2000 server.
- Files with a .bak or .tmp extension, or files that begin with ~. Note that file and folder filters can be modified in Active Directory by using a suitable editor such as Ldp.exe (a Resource Kit utility) or Adsiedit.msc.
- EFS-enabled files and folders. EFS-encrypted files are computer-specific and are excluded from replication.
- Changes to a file or folder's last access time.
- Changes to a file or folder's Archive bit.
- NTFS mount points.
