As you can see in next picture, i have two host with some standard probes (CPU, Memory, Disk, all windows all WMI), and their probes are 5 minutes in error, and 5 minutes are ok. All servers are on same switch, so it is not network issue. PRTG is version 220.127.116.117.
Link how it looks (all sensors are the same) is: http://www.sistemi.hr/files/prtg-error1.JPG
Can you please help?
Thx in advance!
