This rule queries the performance counter "DFS Replicated Folders\Conflict Folder Cleanups Completed" on monitored computers every 15 minutes. Every time the contents of the Conflicts and Deleted folder are cleared, this performance counter is updated. Monitoring the space utilization of the Conflict and Deleted area helps ensure that there is enough space to store replication conflicts and files deleted from replicated folders on the monitored computer. You can view a log of conflict files and their original file names by viewing the ConflictandDeletedManifest.xml file in the DfsrPrivate folder.
Frequent cleanup operations indicate that files in a replicated folder are frequently being modified on multiple servers in a short period. When multiple users need to modify the same files at the same time on different servers, use the file check-out feature of Windows SharePoint Services to ensure that only one user is working on a file.
