I agree with thecadmanan, I work in an office with 60+ CAD users and we have been running C3D 2009 since Jan now and all of a sudden we have about 5 users that are getting this Background Plot Request Failed message. So right now I can plot using SSM just fine but the user next to me can't? this makes no sense.
"All of a sudden" is usually a clue something changed on the systems or network. Work with your I.T. (or if that is you, bring in an outside consultant) to figure out why all-of-a-sudden happened.
Software does not just break one day, there is always a reason.
well all of a sudden is just 5 users out of 60+ so i find it hard to believe that it is a network issue is everyone else is running fine. I am going to try to repiar their CAD and if that doesnt work then maybe reinstall.
Exactly, all-of-a-sudden is a change those 5 experienced: so out of 60, something unique only happened to them. Makes it easier to find the culprit. Good luck with the hunt, look beyond a reinstall IMHO, start with a system restore.
