So, I have ERA server up and running for several months, everything was just fine. ERA client was also working fine, with monitoring, pushing instalations, and stuff. Than 4 days ago, some 15-20 clients got stuck with 3525 update, and stayed that way in ERA client. The thing is, all of them are updating just normally off the local HTTP, and on the computer itself database is the most recent one, but on ERA client they are not identifying, and at the present moment it says they are Last Connected 4 days ago. I looked for anomalys, but they are fine. Just the same as other computers in the network that are authanticating to ERA server just normal. So I thought, maybe I'll erase them, and they will authenticate themselves again in 2-3 minutes, but when i click on delete i get this message: An error occurred. (20009,1) and that's all. No way it's letting me delete them. My server and client versions are the latest (upgraded but that did not help also), 2.0.110 both. Does anyone have any idea what to do?
