Broken WSUS on SCCM

Question

our wsus component of SCCM is broken. We went thru the process of uninstalling/installing WSUS and its failing at the post installation steps. The strange thing is that after it fails wsus still launches and SCCM can do its sync.

This is the log. I have tried running the command version of the post installation and i get the same result.

Apart from going sort of nuclear and removing wsus again, is there anything else i can try? I have followed this post for ideas

Answer 1

Try using my guide's removal and reinstall commands:
https://www.ajtek.ca/wsus/how-to-remove-wsus-completely-and-reinstall-it/

If that still doesn't work, what's the postinstall command you're using?

Answer 2

Did you previously try deleting the WSUS Administration website like indicated in my guide (#3)?

Answer 3

@NP
Please follow the below steps to remove the WSUS role completely first and then we could try to reinstall the WSUS role:
To remove the WSUS completely, you need to:
a. Remove the following server roles and features through Server Manager:
Roles: Windows Server Update Server
features: Windows Server Update Services Tools(at Remote Server Administration Tools -> Role Administration Tools)
Follow the wizard prompts to complete the deletion. Then restart the server.

b. After the server is restarted, manually delete the folder or file of the following path:

• C:\WSUS (this depends on where you choose to install the WSUS)
• C:\Program Files\Update Services

c. Delete database files
If you use SQL Server Management Studio to delete a database, you can try as follow:
In Object Explorer, connect to an instance of the SQL Server Database Engine, and then expand that instance. Expand Databases, right-click the database to delete, and then click Delete. Confirm the correct database is selected, and then click OK.

If you use a WID database, it is recommended to delete the following path folders:
C:\Windows\WID

d. In the IIS Information Services (IIS) Manager, manually remove the WSUS Administration site. Then restart the server.

Please consider restarting your computer and then reinstalling WSUS after finishing above steps.

Best regards,
Rita
