I’ve got an SBS 2011 Standard server that’s been in service for a bit over two years.
During most of that time, the server has frequently received automatic notification of various security fixes and other updates via Windows Update. (The server is configured to automatically download updates but not install them until instructed to.)
Lately however, it occurred to me that the only updates the server has receiving notifications about are the monthly updates to the Exchange Anti-Spam filters.
So I checked the server’s update history, and sure enough, 5/26/2013 is the last time the server got an update other than the Anti-Spam one.
I then clicked within WU to manually check for updates, and now it reports 5+ months worth of updates-- 9 important and 51 optional updates available for the server.
I’m unaware of any reason why the server would suddenly stop receiving update notifications, and I'm not really sure how to go about troubleshooting it.
Does anyone have any suggestions on how to make this server receive automatic update notifications and downloads again?
