WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
After you apply this hotfix, you can add a new NoRemoteRecursiveEvents value to the Windows registry to turn off Change Notify requests for file and folder changes that occur in subfolders of a mapped network share. When you set this registry key, the server still sends a Change Notify event when a file or 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 sub-folder or deeper of the mapped network share. By default, the setting for the NoRemoteRecursiveEvents value is 0. You can add the NoRemoteRecursiveEvents value to either of the following registry keys: or If you add NoRemoteRecursiveEvents value to the HKEY_CURRENT_USER hive, the setting is applied only for the currently logged on user. If you add the NoRemoteRecursiveEvents value to the HKEY_LOCAL_MACHINE hive, the setting is applied for all users who log on to the computer.
