I changed my Administrator password and now my sensors stopped working

However now most of my sensors (all but Ping, HTTP, and RDP) are now in a down state with the following error (I added * for the User and domain):

WMI: Connection could not be established (80070005: Access is denied - Host: , User: *, Password: *, Domain: ntlmdomain:*) (code: PE015). It appears that you are experiencing some difficulties with WMI or related areas. For more information, please see our knowledge base: https://helpdesk.paessler.com/en/support/solutions/articles/60153 -- PerfCounter: Could not log in using the specified credentials. Please make sure they are not only valid for the target system, but for the probe system as well. (Performance Counter error 0xB0000004)

Hello,

You will need to update the password in PRTG if PRTG was using that Administrator account for WMI access.
