CAUSE ===== This problem can occur because Server for NFS ignores the default cache-update settings in the registry for updating the User Name Mapping service. The following registry key holds the settings: HKEY_LOCAL_MACHINE\Software\Microsoft\Server For NFS Mapping\CurrentVersion Registry Value: CacheRefresh Data Type: DWORD Range: 300 to 86,400 seconds (5 minutes to 24 hours) Default: 1,800 seconds (30 minutes) If you change this registry key, there is no effect upon the User Name Mapping service because the settings are completely ignored. RESOLUTION ========== 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. To work around this problem, use either of the two methods: - Restart the server. - Stop and restart both Server for NFS and the User Name Mapping service: a. Start the Services for UNIX Administration tool. Right-click "Server for NFS", and then click Stop. When the service has stopped, click the start option from the same menu to start the service. b. Repeat the same process for the User Name Mapping service. STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft products that are listed at the beginning of this article.
