So I configured my Enterprise 5 server to have NFS configured on specific ports via the NFS Server menu option.
Since having done that, I am unable to get my two CentOS 5 workstations to bind via YP. One worked just fine before the port reconfiguration, but broke after. The other never worked fine.
NFS works fine on both, but NIS will no longer bind.
What do I need to change on the client side to permit binding? I presume the port changes are the problem, and solution.
Thanks.

What is the output of 'rpcinfo -p' on the NIS clients and server?

I'm using http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch30_:_Confi... as a guide and the services all show appropriately on the production server and client, and on a working test setup that is identical to production.
The test setup works flawlessly.

Do you have any firewall setup on the server and/or clients?
What does 'rpcinfo -p' give on the server and clients?

Disabled all around.

Exactly what the referenced URL says should be running.
Again, it works perfectly on a test setup. I may start to use tcpdump for more details. /var/log/messages shows nothing. I can ssh back and forth fine between client and server, so Ethernet connectivity works fine.

It would still be handy to see what they are ...

What happens when you type (on a client):
ypwhich
If that works:
ypcat passwd (or another map)

I did discover tcpdump produces an ICMP host <hostname> unreachable error during ypbind, but does NOT do so when ypbind is not running.
I also was reminded the firewall on the server is running, but I had these exact problems when the firewall was disabled.
Trying to track down the problem via google, and am open to any responses people have here...
Thanks.

What does your /etc/nsswitch.conf file contain?

#/etc/nsswitch.conf passwd: files nis shadow: files nis group: files nis
I also was reminded to perform ypinit -s server and was reminded again of the Can't enumerate maps error. ypinit -m on the server has been performed numerous times, but still nothing...

What's the entry for hosts?

'ypinit -s server' is only needed for slave servers.
