The File Replication service (FRS) is a multi-threaded, multi-master replication engine that replaces the LANMan Directory Replication service (LMRepl service) in Microsoft Windows NT versions 3.x and 4.0. Windows 2000-based domain controllers and servers use FRS to replicate system policy and logon scripts for Windows 2000-based and earlier clients.
Optionally, FRS can replicate content between Windows 2000-based servers that host the same fault-tolerant Distributed File System (DFS) roots or child-node replicas.
This article describes a code change in the Q307319 release of Ntfrs.exe that causes files and folders in FRS-replicated trees not to be replicated. Administrators may experience any of the following symptoms:
When it processes a change order on a downstream partner, Ntfrs renames the matching staging file in a pre-installation folder to its destination file name and folder. Previous versions of Ntfrs may encounter sharing violations during the rename operation if the destination folder is locked by other processes such as Explorer.exe.
To avoid sharing violations, the Q307319 version of FRS opens parent folders with reduced access requirements (FILE_READ_ATTRIBUTES instead of GENERIC_READ and GENERIC_EXECUTE). In doing so, the relaxed folder locks avoid sharing violations that prevent the rename operation from completing. However, this exposed an incorrect access check in the Ntfs.sys file system driver. The incorrect access check in the Windows 2000 Ntfs.sys rename path was fixed in Microsoft Windows XP. This fix prevents file renames by a service such as Ntfrs, even if the service has sufficient rights (in this case, backup/restore rights).

To avoid replication problems in which System does not have full control of the FRS replica tree, install this Ntfs.sys hotfix on all Windows 2000-based domain controllers and member servers on which the Q307319 release of Ntfrs.exe is installed. After you install this hotfix you must restart the computer.
To work around this problem without installing the hotfix, select a member of the affected Ntfrs replica set (preferably a bridgehead server with many outbound connections). Grant the System account full control of the all of the folders in the FRS replica tree by using these steps:
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 3.
