Mappings do not reflect changes made to
advanced user and group mapping.
The User Mapping Server has not refreshed the new mappings. The cache
refresh rate by default is set to update every 30 (1,800 decimal) minutes. This
rate can be changed with a registry edit. The location is:
HKEY_LOCAL_MACHINE\Software\Microsoft\Server for NFS\CurrentVersion\Mapping
"CacheRefresh."
The possible refresh rates range from a minimum of 15 minutes to a maximum
of 24 hours.
NOTE: Setting the refresh rate too low can affect performance due to the frequency of the
updates.
The NFS Server can be refreshed immediately by running the Refresh NFS
Server Setting script in the SFU section of the MMC or by stopping the NFS
service and the User Mapping service. Restart the user Mapping service, and
then restart the NFS Service. Restarting the TaskSmart N2400 appliance also
accomplishes the same thing.
NOTE: Notify all users that are connected before stopping any services.
