Issue with false alarm - Windows Updates - issues with multiple servers



Dear all,

We have the prtg on large screens here in the office and we are just showing the alarm section,

We all see the following alarm : 1 # (Updates (Unclassified) Missing) is above the warning limit of 0.20 # in Updates (Unclassified) Missing

I have checked all the 5 servers the alarm is showing on but there is NO new update . All of the server are Windows 2019 . However the alarm is still there and will not go away.

I did the following ps cmd .

PS C:\> $searcher = (New-Object -ComObject Microsoft.Update.Session).CreateUpdateSearcher();$searcher.Search("Type='Software'").Updates | Sort-Object -Property Dates -Descending | ft -autosize IsInstalled, MsrcSeverity

IsInstalled MsrcSeverity
----------- ------------
       True Critical

Any help or idea are really appreciated

Hi there,

It may help to take a closer look at the sensor results here. Therfore, please enable "Write result to disk" in the sensor's "Settings" tab. With the next scan it will write one or several result-files into C:\ProgramData\Paessler\PRTG Network Monitor\Logs\Sensors of your PRTG server (or on the Remote Probe if applicable). All files have the sensor's numeric ID in their filenames. The sensor ID can be found on the sensor's "Overview" tab.

If you want us to analyse those, I would recommend to open a support case, since it is easier to handle that way.

Kind regards,
Birk Guttmann, Tech Support Team
