you can try this:
1. Queries & Reports
2. Result Type: Managed Systems
3. Chart: Pie Chart, Labels = "Handler DNS Name", Columns = Add Handler DNS Name
I tried the above query from one epo and when i select the Agent handler i am getting only that server dns name and other epo dns name is not showing.
(There are two epo for the two servers ,how can i perform now?)
does that ePO Server "see" all Clients? If not, this query will only show the agents it manages and clients, which are unmanaged, but registered to this server.
