Event Id 1014 DNS Client

I get this warning in the Event Manager intermittently

name resolution for the name.........timed out after none of the
configured DNS servers responded.

The name that has repeats is www.lemontmarte.ca although there are
others of which I have not been to these sites.

I have searched up and down to see if it is cookie related, or whatever.
AVG is installed with all parts active.
I did an online scan with ESENT yesterday and no result.

This sort of warning never appeared in the Event manager with Xp.
I have run out of search ideas.

What should be the response to doing something about this warning?
