Tons of thanks to all..i got more than 12 responses in just half an hour.i 
delayed posting the summary for I wanted to test the procedure.the following 
procedure worked fine wjich was suggested by many.
Here is an additional tip from   Mike DeMarco (thanks mike!)

You should be real careful about eliminating all of your slaves.
	1) nis bind requires a broadcast and since you can not broadcast across 
subnets a client can not sit on a different subnet from the server. (Unless 
you manually bind it, this is
	2) If your slave goes down there will be no other maps availableand all 
clients will stop until the slave is restored to service.
	3) with many clients you could overload the slave.

how to tell if the host is a slave or client:
	On boot up the system looks for the directory /var/yp/<domainname>
	if it is there it will start the ypserv daemon. So you could look
	into /var/yp and see if there is a directory there or you could do
	a ps -ef | grep ypserv.

To stop a node from being a slave:
	If your master pushes the maps out you must remove the slaves host
	name from the ypservers map. This map usually does not have a flat
	file associated with it so on the server you must do a
	ypcat -k ypservers > /tmp/ypservers
	then edit the file /tmp/ypservers and remove the entry for the slave
	that is to be removed.
	now you will have to do
	makedbm /tmp/ypservers /var/yp/`domainname`/ypservers

	This will stop the pushes from going to the slave you are removing.
	Now go to the slave and run ypinit -c
	add to the list the name of the slaves that you would like this host
	to bind to.
	Now run /usr/lib/netsvc/yp/ypstop
	now remove the /var/yp/<domainname> directory or rename it to something
	Now run /usr/lib/netsvc/yp/ypstart.
	You should now have a client where you use to have a slave.
