What is "AV update delta" in Policy manager - Status - Automatic updates?
Most computers have 1 hour but some have >100 hours even if they are online and connected.
"delta" is the difference between last status update and AV-Updates, when the status was generated. last staus update is listed as last connection time.
when a (rarely used) machine boots up it sends a status, befor it has finished installing updates. Has the machine been shut down again before the next status update the difference may be 100h.
What F-Secure version are those systems?
What is the local information on those systems?
These problem PCs have old AV updates and nothing helps but to manually run fsaua-reset tool. FCS version is 9.31. The local log says something like connected to server but nothing new available.
Looks like you have to check for updates every once in a while. Some problems are fixed when updated, but some problems are made on the same process.
