Dear All,

From our WSUS server event log, we have a lot of error message showing "Many client computers have not reported back to the server". I crossed check some of the computers and they are actually contacting to WSUS server well - https:wsus:8530 is accessible. Any idea why this happened and any actions are required to take?

Any help would be really appreciated.

    Hi @EavenHuang-0590，

    I notice the error event ID is 13032, we may refer to the below steps to check related configurations (please backup the IIS database first before we make below changes):

    1- Gave Full Control to NetworkService in:
    1a.<> C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG
    1b.<> C:\Documents and Settings\Default User\Application Data\Microsoft\CLR Security

    3- Change password of IUSR user

    4-Remove Integrated Windows Authentication in the following WSUS Sub-sites in IIS console
    4a.<> to do that click start --> run and type inetmgr and the console of IIS will open, navigate to the WSUS Administration web site
    4b.<> Expand WSUS Administration
    4c.<> Right click on ClientWebService and them properties
    4d.<> Click on Directory Security TAB
    4e.<> Click on Edit button from the Authentication and Access control
    4f.<> Set the password you've changed on step 3
    4g.<> remove Integrated Windows authentication
    4h.<> click OK twice

    5- Repeat the steps 4c to 4h to the following web sites

    • Content
    • DSSAuthWebService
    • Inventory
    • ReportingWebService
    • SelfUpdate
    • ServerSyncWebService
    • SimpleauthWebService

    6- Run the comand "IISReset /noforce"

    7-check if The WSUS clients start to synchronize with SBS Server and report normally now.

    And here is the similar post we could refer to:

    Hope this helps.
