Why when I right-click on the “Update Repository” Console item under “Software Updates” do I not see the “Run Synchronization” option?


This is because you are trying to initialise the sync from a Site that is synchronising from an upstream Site. For example a Child Primary where the Central Site is configured to synchronise with Microsoft¬†Update. The “Run Synchronization” option is not available on a Site configured to “Synchronize from an upstream update server” (you can easily check this by double-clicking the “Software Update Point Component” under “Site Management | (<site_code> – <site_description>) | Component Configuration” and clicking the “Sync Settings” tab which will show the Software Update Sync Settings for this Site).
