I keep getting reports of systems being removed from zenworks database. The only solution seems to be to go back to each device and do zac reg htt:\\server to get it back in.
Under the main configuration under Device refresh schedule i did have it remove devices after 30 days. Some of the systems we surely on in that time, and they were removed. About 2 months ago i change it to flag devices after 30 days.
I am still getting reports of systems being taken out. I am running zenworks 10.3.1 on 6 primary servers all talking back to our 2008 windows r2, running sql 2005.
Am i missing anything?

thanks so much!
