Do you have duplicate IPs in your Nodes table?
SELECT COUNT(IP_Address) AS IP_Count, IP_Address, Caption
GROUP BY IP_Address, Caption
HAVING (COUNT(IP_Address) > 1)
I just checked and didn't see any duplicates. Unfortunately, I can't tell if this is an old problem or not. The earliest I see is November...
I was mistaken. I ran another query and found 6 duplicates. I will fix that and hope the warnings go away!
Here's the query I used:
SELECT Nodes.IP_Address AS IP_AddressChamps, Count(Nodes.IP_Address) AS NombreDeDbls
GROUP BY Nodes.IP_Address
