Setting the host name for an NIS+ server to be fully qualified is not recommended. If you do so, and NIS+ queries then just hang with no error messages, check the following possibilities:
Fully qualified host names must meet the following criteria:
The domain part of the host name must be the same as the name returned by the domainname command.
After the setting the host name to be fully qualified, you must also update all the necessary /etc and /etc/inet files with the new host name information.
The host name must end in a period.
Stop the NIS+ service and any associated processes that are hanging on that host or server. Rename the host to match the two requirements listed above. Then reinitialize the server with nisinit. (If queries still hang after you are sure that the host is correctly named, check other problem possibilities in this section.)
