If you open a folder to a network share on a Windows Server 2003 server and then perform a Network Monitor trace, you may notice that server message block (SMB) keepalive packets are sent every 32 to 33 seconds.
Note Excessive flickering can also be caused by antivirus software or by another third-party program that constantly updates the folder or the folder tree on the server that clients are connected to.

- Entry name: NoRemoteRecursiveEvents
Value data: 0 (the default) or 1
A setting of 1 for this registry entry turns off Change Notify requests for file changes and for folder changes that occur in level 2 (and below) subfolders of a mapped network share. The server still sends a Change Notify event when a file or a folder is changed in the root of the mapped network share. However, the server does not send a Change Notify event when a change is made in the second subfolder or in a deeper subfolder of the mapped network share. By default, the setting for the NoRemoteRecursiveEvents registry value is 0 (zero).
- Entry name: NoRemoteChangeNotify
Value data: 0 (the default) or 1
A setting of 1 turns off Change Notify requests for file changes and for folder changes on mapped network shares.
Note If you set this value to 1, change notifications on network drives are disabled. You must press F5 or click Refresh on the View menu in Windows Explorer to manually update the changes in the current folder of a network share.
