Synchronizing and propagating NIS changes
A Windows-based master Network Information Service (NIS) server can propagate changes in maps to subordinate NIS servers in the same domain. These changes are propagated to subordinate NIS servers using the features of the NIS protocol.
The master NIS server supports the following transfer modes:
Periodic transfer of NIS maps.
On-demand transfer of NIS maps to subordinate servers. Typically, NIS maps get transferred to subordinate servers upon change by using make. The Windows-based NIS server does not use make; instead, the server pushes immediately.
Subordinate NIS servers can request transfer of maps at any time.
