Where are you reviewing the logs? Who is logging it, ie does Etrust create it's own log or does it dump it into event viewer under applications or something. It may be possible that local logging is not enabled to either. I bet you checked that already but I have had to tweak Mcaffee to log properly through a domain policy on logging.

//Edit, oh I saw your last post to late. I tweaked mine to log start and stops of scans so I can quickly make sure they are at least running. etrust might not do that, but you should be able to see the service start up in the windows logs.

I've never liked CA products even though I've had to install and use them at various jobs. I've noticed this same issue but with their backup software. It'll fail for no reason, then not give any notifications that it did or the reason why. It didn't even give one of those meaningless CA error numbers.
Ahhh, that thing blows. Korp what are you using or would use as a replacement? My contract runs out and I can't stand to look at CA, Arcserve, Brightstore, whatever another f#c3ing day.
