Hi, @lalajee

Thank you for posting in Microsoft Q&A forum.

2023-05-19 15:42:43 Start: GetConfigValue with filename=UpdateServices-Services.xml item=ContentLocal

Please try renaming file name UpdateServices-Services.xml to updateservices-services.xml.old. Then run post-install again.

(UpdateServices-Services.xml is under c:\windows\system32\servermanager\componentconfiguration)

If issue persists, please try to remove wsus role , wid, delete database file, reinstall wsus again.

Hi, @lalajee

You may check Change.log under C:\Program Files\Update Services\LogFiles to see why the sync fail.

After download and install report viewers, did you reopen the WSUS console?

Hi! @AllenLiu-MSFT

I'm having the same problem as the one listed above, and i tried everithing, for whatever reason, when i reinstall WSUS, some folders on C:\Program Files\Update Services, as tools folder, do not exist. The only way to make them appear, is running sfc /scannow.

I have tried to rename UpdateServices-Services.xml file and run post installation tasks after renaming it, and it didn't even create a new .xml file

Network Service has permissions to modify on C:\Windows\System32\ServerManager\ComponentConfiguration so i don't know what could be the cause

I've performed a clean reinstallation many times, cleaning Registry keys, deleting content and installation folders, detatching the SUSDB database and deleting SUSDB.mdf files, deleting Application pool from IIS and WSUS site, removing WID, and installing it again (Even deleting WID folder)

My UpdateServices-Services.xml file content is the following:

<?xml version="1.0" encoding="utf-16"?><INSTANCE CLASSNAME="ServerComponent_UpdateServices_Services"><PROPERTY NAME="ContentDirectory" TYPE="string"><VALUE>T:\WSUS</VALUE></PROPERTY><PROPERTY NAME="ContentLocal" TYPE="boolean"><VALUE>true</VALUE></PROPERTY></INSTANCE>

The T:\WSUS folder exists and Network Service has modify permissions, so it should not be the problem

Thanks in advance

Did you follow the instructions on : https://www.ajtek.ca/wsus/how-to-remove-wsus-completely-and-reinstall-it/

??? Under "Troubleshooting Steps If You Still Have Problems:"

It has this specific issue:

If you are having issues because the C:\Program Files\Update Services\Tools\ folder doesn’t exist,....

I finally solved it by deleting a file located on %appdata%\MMC\ named WSUS

Once i deleted this file, and performed the steps on your guide to uninstall it and install it again, it worked.

Seems like the server was updated from previous OS versions, and still had the old MMC file for WSUS. Once i deleted it, all the problems i had on the installation, with folders missing, and post installation errors were solved

Thank you for all your feedback and help to the SCCM community, you've helped me in numerous bad scenarios

Thanks again!

Struggled with this myself for quite a while. Logon as the default local administrator account. Delete your content directory if it already exists (i.e. D:\WSUSContent). Recreate the directory while logged in as the local administrator and then try again
