avn,
I have adjusted report a little bit, so, it now does what it should be doing. Thank you so much for your help
SELECT DISTINCT NodeID, Caption
FROM Nodes
Where NodeID not in (SELECT Nodes.NodeID FROM Nodes, APM_CurrentStatusOfApplication
Where Nodes.NodeID = APM_CurrentStatusOfApplication.NodeID and
APM_CurrentStatusOfApplication.ApplicationName LIKE '%Basic Windows Server Checks%')
And Nodes.MachineType LIKE '%windows%'
