You can view NIS servers with this command. ypwhich returns the name of the NIS server that supplies the NIS services to a NIS client.

[root@server ~]# ypwhich 
server3.nyc
[root@server ~]#

This command will show the yp configutation file for the server listing all available nis servers. As well as the NIS domain name.

[root@server ~]# cat /etc/yp.conf
# /etc/yp.conf - ypbind configuration file
# Valid entries are
#
# domain NISDOMAIN server HOSTNAME
#	Use server HOSTNAME for the domain NISDOMAIN.
#
# domain NISDOMAIN broadcast
#	Use  broadcast  on  the local net for domain NISDOMAIN
#
# domain NISDOMAIN slp
#	Query local SLP server for ypserver supporting NISDOMAIN
#
# ypserver HOSTNAME
#	Use server HOSTNAME for the  local  domain.  The
#	IP-address of server must be listed in /etc/hosts.
#
# broadcast
#	If no server for the default domain is specified or
#	none of them is rechable, try a broadcast call to
#	find a server.
#
domain itm server server3.nyc
ypserver server2

[root@server ~]#

As for updating slaves nis from master you will issue the make command from /var/yp on the master server.

Hope this helps. Also have a look at man pages for all nis related commands.
