Console Message - YP server not responding, still trying

Question

I am getting the following message in the CONSOLE MESSAGES app. It repeats every 10 seconds. The IP that is not responding is my old Windows PC that was connected to my router before I bought my iMac.
How can I stop the computer from trying to connect to this IP address?

Answer 1

I found this response to the same situation on OSX
10.5 and I am wondering if this is safe to carry out.
Am I going to run into any problems if I do this?
{quote}A fix for the ypbind errors in system log
OS X 10.5 Leopard is showing these errors every ten seconds:
] com.apple.nis.ypbind[]: Domainname not set. Aborting.
] com.apple.launchd[1] (com.apple.nis.ypbind[]): Exited with exit code: 1
] rasalas-pro com.apple.launchd[] (com.apple.nis.ypbind): Throttling respawn: Will start in 10 seconds
I fixed it as follows:
Since ypbind is not used by OS X in 99.9% of installations, just turn it off.
Edit the ypbind start-up definition
sudo vi /System/Library/LaunchDaemons/com.apple.nis.ypbind.plist
and change
<true/>
to
<false/>
Then shutdown the service
sudo service com.apple.nis.ypbind stop
I'm expecting that the "false" will keep it from restarting on reboot, but not quite sure about that.
Also, for future reference
sudo service --list
will show all the 'services'...
