After updating PRTG as of 18.104.22.1681, many WMI sensors in my PRTG installation suddenly show the Down status. They also show the error code PE263 with this message:
The sensor was not able to establish a connection for more than three successive scanning intervals. The reason might be corrupt performance counters or a damaged WMI stack on the target Windows system. To resolve this issue, see https://kb.paessler.com/en/topic/72969. (code: PE263)
Where does this error come from? Have you changed something in PRTG that causes this issue? How can I fix error code PE263?
