Slave server NIS woes

[Jennifer Tippens]

Hello, 
Was wondering if anyone ran across this type of thing before and could give advice?  
I made a NIS domain on our lan behind the firewall.  I have ypserv running and ypbind (on the server) is bound to the localhost.  I have a client that pulls the information off of the server.  I wanted to make that client a slave server, but when I did a "ypinit -m" on my master server, it times out on "Updating netid.byname" (says: netid.byname-> myslaveserver.mydomain.int: Callback timed out) and it exits with error 2.
When I ran ypinit -s mymasterserver.mydomain.int, it said "Can't enumerate maps from mymasterserver.mydomain.int. Please check that it is running."  It _is_ running.  In /var/log/messages, it says: myslaveserver ypserv [9545]: ypproc_xfr: refuse to transfer map from 192.168.1.2, no valid domain.  The ip number is the correct ip number for the master server. 
Can anyone please help me with this?

Thank you!
