Below is a summary of my post of two days ago. I was trying to set up
some new slave servers that were on a different segment of ethernet from
the master and existing slave servers.
The correct reply came from John Shin(sp?) at Sun:
be in single user mode
run portmap
set new domainname
run ypbind -ypsetme <<<<<------ this was the key
run /usr/etc/yp/ypset A.B.C.D ( Internet address of NIS master )
cd /var/yp
/usr/etc/yp/ypinit -s <master>
Below are all the answers and my original post at the bottom.

are you trying to do this from single-user mode?
if so, is the master in the slave's host file?

hi,
i seem to recall (isn't human memory fuzzy ;) having the same kind of problem.
the solution was
mkdir /var/yp/<domainname>
on the slave server.

1. Are you running ypinit -s *mastername*' ??
2. If so, there are several scripts in '/usr/etc/yp' that use ypxfr to transfer
maps from a master to a slave. Try running them on the slave servers.

are you running ypserv on the master server?
running ypinit may have killed it.

Kes,
Try this on your master server:
syrinx# ypcat -k ypservers > /tmp/ypservers
-- edit /tmp/ypservers to add new slave name --
syrinx# cd /var/yp
syrinx# cat /tmp/ypservers | makedbm - /var/yp/`domainname`/ypservers
Now you can run *ypinit -s* to initialize the slave server, and then ypserv
to provide service to clients. ( Nod to Mr. Stern's fine "Managing NFS & NIS" )

From: Christian Lawrence <cal@soac.bellcore.com>
It sounds like there's a mix up resulting from the conversion from the old
domain to the new domain. Check that /etc/defualtdomain is correct. Check
that you have moved the old database dir (/var/yp/<YP.domain>) to something
not confusing (e.g. /var/yp/old.<YP.domain>). Then go to single user, make
sure the portmapper is running, and try ypinit -s again (making sure that
you have an entry in the local /etc/hosts to map the master address/name.
It should work !

>From your short description it seems that you might have forgot to run
/usr/etc/ypbind. You have to do this before executing ypinit -s venus.
Hope it helps.

My original question:
Hi,
I'm looking for some help adding new slave servers. I have several
slave servers running now and I'm trying to add some more. I ran ypinit -m
on the master and added the new slave servers. I can do a ypcat ypservers
and see the proper list. I also can rcp files from the master to the
machines I want to be slaves, so I know the connection is good. When I run:
ypinit -s <master>
I get:
Can not enumerate maps from <master>. Please make sure <master> is up.
I can telnet and rsh from the slaves to the master. The slaves we are
trying to add were previously running on a different domain, but the
domainname *was* changed to the new domain name.
Configuration: 4/490 running 4.1.1 as my YP master
several 3/180(4.1.1) and a 690(4.1.2) running as slave servers
trying to add a 4/490(4.1.1) and 3/180(4.1.1) as slave servers
Any suggestions?
Thanks for the help,
