High network usage after you implement file screening on a Windows Server 2012 R2-based Work Folders sync server

Applies to: Windows Server 2012 R2 DatacenterWindows Server 2012 R2 StandardWindows Server 2012 R2 Essentials More

This article describes an issue that occurs on a Windows Server 2012 R2-based Work Folders sync server. You can fix this issue by using the update in this article. Before you install this update, see the Prerequisites section.

Symptoms


High network usage may occur when the File Server Resource Manager (FSRM) file screening is implemented on the Work Folders sync server to block certain file types. For example, audio or video files, image files, executables, system files, and Outlook data files.

Cause


This issue occurs because the FSRM file screening blocks the file(s) when they are transferred to the Work Folders sync server. The Work Folders service then tries to re-sync the file(s), which causes increased network usage.
