I believe that AVAST has a superior product, and am trying out their complete set, but with the lack of quality support in identifying these issues, I may jettison this trial and look at another product. >:(
please let me apologize for not getting back to you earlier.
The two log entries you posted basically mean that the agent was having problems contacting the management server (I assume 192.168.0.50 is the right address of the AMS…is it?). If these entries are not too numerous, you probably don’t have to worry about it (it can e.g. mean that the AMS was down because of a routine maintenance). If the entries are repetitive, it may mean that more investigation is needed…
