Last Windows update sensor

Hello,

please make sure that the "Remote Registry Service" is running on the target system. Please also consider updating to the latest version of PRTG (12.4.6).

best regards.

Hi Paul,

In addition to what Torsten already mentioned, please also check the credentials the sensor is running on. You can set these credentials on the parent device under "Credentials for Windows Systems"

Hi,

I have tried different domain administrative credentials and the Remote Registry service is running but the error still exists.

Many Thanks

same here, core server is not in domain of the servers which are monitored. But the windows update sensors always worked and now it's saying that the credentials aren't correct. This was one of the main features why we bought PRTG.

Please consider then using Remote Probes to run the sensor within one domain.

Credentials used need to be valid on both your PRTG server (or probe) AND the target machine.

The sensor first uses these credentials locally to create a security token. Next this token is used targeting the remote machine, that’s why the credentials need to be valid on the remote machine also.

• Being on a domain, using a domain account will be the easiest way to accomplish this, as a domain account is usually valid on every machine in the domain and you don't need to worry about password changes.

• Outside a domain you need to use a username and password that are identical on both probe and target. So make sure that username x with password y is valid on probe and target. When you decide to change the password, keep in mind that this has to be done on every machine that uses the credentials in case.

Username and Password are entered in the Windows Credentials of the parent device. If not both probe and target are in a domain, leave the domain field empty and use local credentials.

Hi Gerard,

I can confirm that the credentials are set on the probe, other sensors are working correctly such as cpu and memory for the same server that is having last windows updates issues.

Please can you give a list of registry permission's and folder permission's so I can check against other working servers within the same domain.

Many thanks

Hi Paul,

The sensor checks registry key

SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install

and uses the value from the "LastSuccessTime"
