When Server Preferences Take Effect

Changes you make to a machine or subnet's server preferences normally do not take effect on a given machine until that machine updates it nis_cachemgr data. When the nis_cachemgr of a machine updates its server-use information depends on whether the machine is obtaining its server preferences from a global client_info table or a local /var/nis/client_info file (see "Global Table or Local File").

However, you can force server preference changes to take effect immediately by running nisprefadm with the -F option. The -F option forces nis_cachemgr to immediately update its information. See "How to Immediately Implement Preference Changes" for details.
