Ypproc_match connections refused

[terrywashington]

I am seeing the below errors on all six of my NIS slave servers. All are running RH 8.0. The NIS master is running Solaris 2.6.and does not have the errors. I tried stopping and starting the portmapper on the slaves yet the errors continue. Ports 22, 25 and 80 are the only open ports on the NIS slave servers. The NIS slaves are refusing connections from Solaris NIS clients. There are no errors on the NIS clients and they are having no problems binding to the NIS slaves. Has anyone seen this before?
