We just installed ESET at one of our client sites, 23 machines. They ran fine for a few weeks and then suddenly 13 of them lost their ESET usernames and passwords. The ERA console shows them all failing to update, invalid username and password. That is frustrating enough. Now I can't push out config files to any of them. I created an xml with the ERA server name, username and password and I follow the instructions on this page exactly: http://kb.eset.com/esetkb/index?page=content&id=SOLN2204&act=RATE&impressions=false&newguid=050019703f25dac1012e7285c3de007fd2 The task immediately fails with "no task for this client" on each of the clients. If I do it individually, rather than a batch of clients, it does the same thing. This started three days ago and already one of the PCs that is not updating has a fakeav virus. Any ideas about what the problem is here?
