BEfore i open a ticket, I would like to know what I can do on my end to attempt to resolve the issue. 

We have a few dozen machines that are online, show online. Show recently completed scan dates and times. Yet they don't show who is logged on to them.

We have physically verified computers A, B, C and D are in use by users. Those same computers do not show anyone as being logged in in the dashboard or in the reports of Desktop Central.

The client is up to date, the last scan date, and boot time show this morning.  These users logged into the computers are the daily users of the computers.

Again, before i open a ticket, is there something I need to do or can do on my end.
