No unusual to get the occasional moody WSUS managed-device that will not report and/or update using a correctly configured WSUS server. The link below is the one I like to use to test the connection from the WSUS managed device to the WSUS web site.
Note: The test URL below uses my-wsus-box as the server name and 8530 as the configured port for the WSUS web site – change as appropriate.
Note: If the connection to the WSUS web site is good then a prompt to download wuident.cab should be presented.
Windows Server 2016 would not download updates from WSUS server running WSUS v4.0. Viewing the WindowsUpdate.log the following error was noted:
- HTTP/1.1 403 Forbidden by proxy
Unable to easily view the IE proxy settings as IE had been disabled by Group Policy on the server. Fix was to reset the proxy settings using the following command:
- netsh winhttp reset proxy
SCCM 1511 Site Server requires WSUS Admin Tools to be installed if the SCCM 1511 Software Update Server (SUP) is running on a remote server.
- Install-WindowsFeature -Name UpdateServices-Ui
Or from the GUI.
