Hi,
We have 18 machines running various operation systems (Windows 7/8/10, Windows Server 2008 R2/2012/2012 R2) and most are failing to update automatically. If LiveUpdate is run manually on these machines, they update properly. Most of the time it is the IPS Signatures, SONAR Content, and the Download Protection Content that are out of date, but the Antivirus Content is also becoming an issue. The machines are rebooted vary infrequently due to them being mission critical servers, but when they are it rarely rectifies the issue. Most of the desktops are experiencing the same issues as the servers too, and they are rebooted more often. I don't believe it to be a problem with the SEPM itself because there are some machines that are kept completely up-to-date and they have (more or less) the same configuration as the other machines. I've looked everywhere but have been unable to find a resolution.
Thank you for any help/advice in advance.
