In those cases where a machine does not have Internet connectivity at the time of a machine patch scan, Kaseya uses Microsoft’s WSUSSCN2.CAB data file. Microsoft publishes this CAB file as needed. It contains a sub-set of the Microsoft Update Catalog. As seen in the table above, scan data for only the high priority updates and occasionally for service packs are included in the CAB file. The Kaseya Server automatically downloads the CAB file on a daily basis to make it available for those machines needing this type of scan. See Windows Automatic Update.
