When I said re-init nisserver1, I just meant re-init the NIS environment on it. If you clear out the old maps in /var/yp/binding/DOMAIN_NAME (DOMAIN_NAME = Your NIS domain) directory on nisserver1 and run ypinit -s MASTER_SERVER_NAME where MASTER_SERVER_NAME is the name of the NIS master configured in the NIS maps. This will set the machine up as a new NIS slave server with a fresh copy of the maps from the NIS master. You have to remove the old binding dir before ypinit -s will run for a re-init.

If you don't want to re-init NIS on nisserver1, then depending on which version of UNIX you are running, it is possible to specify which NIS server to bind to. For instance, on Solaris you run ypinit -c and specify a search order the NIS servers for each client. This creates a ypservers file /var/yp/binding/DOMAIN_NAME where DOMAIN_NAME is the NIS domain name. You can edit this file to add/delete/modify NIS servers. If you remove the file completely, the ypbind daemon starts as a broadcast daemon by default.

This behaviour for NIS on most flavors of UNIX I've worked on. If for some reason the flavor of UNIX you are using doesn't support ypinit -c (SCO for instance), you must start ypbind with the -ypsetme flag and use ypset to manually assign an NIS server.

If you tell me what UNIX OS you're running, I can give you specific instructions if you need them.

ypinit(8)						      System Manager's Manual							 ypinit(8)

NAME
ypinit - NIS database install and build program SYNOPSIS
/usr/lib/yp/ypinit [ -m ] [ -s master_name ] DESCRIPTION
ypinit builds the domain subdirectory of /var/yp for the current default domain. After building the domain subdirectory, ypinit builds a complete set of administrative maps for your system and places them in this directory. The first map created by ypinit -m is the ypservers map. You should run it as root on the hosts, which should be the master ypserver. You should have only one master server per NIS domain. All databases are built from scratch, either from information available to the program at runtime, or from the ASCII data base files in /etc. These files are listed below under FILES. An NIS database on a slave server is set up by copying an existing database from a running server. The master_name argument should be the hostname of an NIS server (either the master server for all the maps, or a server on which the data base is up-to-date and stable). OPTIONS
-m If the local host is the NIS master. -s Set up a slave server with the database from master_name FILES
