Hi All,
I know this is an old thread, but we are having the red dot issue with most of our Macs on AD. They are OS 10.11 and had been joined to AD (.edu domain) for a while but we were using local logins until recently. Within a few days of having students login with their AD credentials we started getting the red dots here and there and now mostly everywhere. So, since I don't see recent posts about this, is there an accepted solution to this issue that we're missing? We've tried all the basic things and are getting ready to try extending the mdns timeout, then the script after that.
