Network connection: Windows Update Agent encountered transient network connection-related errors

Hello,

Running the report Scan 3 - Clients of a collection reporting a specific state, I noticed a lot of this kind of error :

Network connection: Windows
Update Agent encountered transient network connection-related errors

I also noticed that the the amout of errors is increasing when new updates are available or deadline reached.Then, the numbers of errors decreases from day to day.

On the client, I've found the following error :

Now going to IIS logs on  the WSUS server found this :

  Status Hits
  200.0 4986427
  500.0 83805
  400.0 3209
  401.2 5

So, a lot of 500.0 status that translates to Internal server error.

Checking, the event log, I found a lot of events Event ID 5013 IIS Application Pool Availability

Event info mention : WsusPool

The time errors 500.0 occurs on IIS match th etime errors are reported by the client.

Also found this in IIS logs :

  Uri HttpStatus SubStatus Win32Status Total
  /ClientWebService/client.asmx 500 0 0 5152
  /ClientWebService/client.asmx 500 0 64 1382
  /ClientWebService/client.asmx 500 0 1236 12
  /ReportingWebService/ReportingWebService.asmx 500 0 0 10
  /ApiRemoting30/WebService.asmx 500 0 0 5
  /ClientWebService/client.asmx 500 0 121 2

Do you have any idea to troubleshoot this error ?

Michel

Hi,

What do you get after enabling failed request tracing on WSUS website?

Have you checked the SUP status from Monitorin workspace in console?

Best Regards,

Joyce

Here is an update.

We have completely uninstalled and reinstalled the WSUS. Do it solved nothing.

We are now investigating the WSUS App pool private memory limit setting :
