Be careful when deleting entries from clients. Good luck.

I've started seeing this message, and the host it is referring to is my
server (among other servers), I think I fix this the same way I fix the
error that says "There is already a machine with that name". That is,

nsradmin -p nsrexec
Delete type: NSR peer information; name: server being complained about

But I haven't been able to confirm that this is what I need to do. Can
anyone tell me if this is what I do, or is there some other method to fix
conflicting NSR peer info?

Thanks
