NIS on Redhat 9

  I have updated all our servers to redhat 9 and now I get several strange 
errors in my /var/log/messages file.
first every 30 seconds or so I see :
ServerA ypserv[1718]: refused connect from to procedure ypproc_match (,netgroup;-4)

then whenever I try to ssh into one of the NIS servers, before I am 
prompted for a password I see this in the messages log:
ServerA sshd(pam_unix)[10180]: authentication failure; logname= uid=0 euid=0 tty=NODEVssh ruser=  user=jrush
Then I am prompted for a password and can login fine.

Does anyone have any ideas as to why this is happening?  I even tried, for 
testing purposes, to add an allow all from anywhere line to iptables and 
it still occurs.

Thanks in advance for help,
