You’re running WSUS (Windows Server Update Services) on Windows Server 2019 Server Core, and you want to run the WSUS Re-Index or WSUS Cleanup script, but you can’t because you cannot install the SQL Management Studio on Windows Server Core.

Well, there’s a way around this. To run SQL scripts on the WID (Windows Internal Database) on Windows Server Core, we’ll need to install “sqlcmd” (info here).

Now normally with Microsoft SQL, you’d simply connect remotely using the SQL Management Studio, and you can if you’re using fully blown Microsoft SQL Server with your WSUS implementation, however most of us aren’t. In most small deployments, WSUS is configured using WID (Windows Internal Database) which is essentially Microsoft SQL Express.

Microsoft SQL Express doesn’t support remote named pipe connections, and there’s no easy way to configure TCP connections with the registry editor, so the easiest way to accomplish executing SQL scripts is to install and use the “sqlcmd”.

Instructions

Install the SQLCMD command utility

  1. First we need to identify the version of SQL express that’s running WID on the server running Windows Server Core 2019.
  2. Open “notepad” and open the following file which containts the WID log.
    C:\Windows\WID\Log\error
  3. At the beginning of the log file, you’ll note the Microsoft SQL version that’s running. In my case it’s “Microsoft SQL Server 2014 (SP2-GDR)” specifically 12.0.5214.6 as shown below.
    2019-05-14 10:52:47.79 Server      Microsoft SQL Server 2014 (SP2-GDR) (KB4057120) - 12.0.5214.6 (X64) 
    	Jan  9 2018 15:03:12 
    	Copyright (c) Microsoft Corporation
    	Windows Internal Database (64-bit) on Windows NT 6.3  (Build 17763: ) (Hypervisor)
  4. The “sqlcmd” is part of the Microsoft SQL Server Feature Pack, so a quick search of “SQL Server 2014 SP2 Feature Pack” returned the following URL:
    https://www.microsoft.com/en-us/download/details.aspx?id=53164
  5. When you click download, you’ll notice multiple files. Choose the ”
    ENU\x64\MsSqlCmdLnUtils.msi” file to download.
  6. Copy this file over to your server running Windows Server Core.
  7. Execute and run the installer. Follow the prompts.
  8. You’ll notice the installer will error and require “Microsoft ODBC Driver 11 for SQL Server”. A quick search finds this download:
    https://www.microsoft.com/en-ca/download/details.aspx?id=36434
  9. Download the above file, install the “Microsoft ODBC Driver 11 for SQL Server”.
  10. Re-start the “MsSqlCmdLnUtils.msi” installer, and it should now complete.
  11. You have now installed the SQLcmd utility.

Run the WSUS Re-Index Script

  1. Download the WSUS Database Re-Index script from:
    https://gallery.technet.microsoft.com/scriptcenter/6f8cde49-5c52-4abd-9820-f1d270ddea61
  2. Copy the script to the server.
  3. Run the following command from the command prompt:
    sqlcmd -S np:\\.\pipe\Microsoft##WID\tsql\query –i C:\Folder\WsusDBMaintenance.sql

You’ve officially installed the sqlcmd and ran the WSUS Re-Index script on Windows Server Core. Congratulations!
