I apologize but I didn't understand the question.
Which report are you running and what is missing in that?
I have 4 computer in the domain but ePO cannot find this computer, all computer have the DAT 6398, but ePO reort that the computer have DAT 6242, and this (DAT deploiement) report print that Ihave the DAT ot March.
I use the ePO 4.0.0 and VSE 8.5i
Sounds like an agent communication problem. Try re-installing the agents and see if that helps.
Barring that, look in your registry under HKLM\Software\Network Associates\ePolicy Orchestrator\Application plugins and make sure you don't have two different Virusscan entries. You should have only one for your VSE version.
