Console App shows errors, how to correct?

I noticed my computer making sounds as if it were running a program when all programs were closed. So I started the utility "Console" and found this sequence showing up and I have no idea what it is and how to stop or remove it.
In console I get the following message every few minutes if not more frequently.
" startLLQHandshake: 3 failed attempts for LLQ _smb._tcp.mcaz.members.mac.com. Polling. "
The above message when viewed in the inspector shows the sender as "mDNSResponder"

I also see this one, but not as frequent, Maybe every ten to 20 minutes

" (Error) ImportPluginLoading: Couldn't load plugin 'file://localhost/Library/Spotlight/iWeb.mdimporter/' "

I have switched to show all hidden files and looked for anything that looks same in name or similar but haven't had success.
Can anyone please advise.
I am running Mac Pro Dual Quad Core with OS X Lion
Any help or suggestions is greatly appreciated.
Thank you in advance
