Which version of VSE are you using?
I believe that you missed to install the VSE extension file to the ePO server.
I use the ePO 4.0.0,
but since 3 months he no longer reflects a good area, for example I have a new machine in the domain but ePO can not find it, all my days are machine but ePO gives me an report that no machine is updated, the latest DAT and DAT update 6398 but in its deployment report has a DAT of March.
Thank you for your cooperation.
please I use VSE 8.5i
You may want to edit the report (Query) used for the VSE DAT Deployment and check the criteria used. If the criteria is not met then the machine is flagged as non-compliant.
but all report is not correct, also the ePO cannot contact the computer. the ePO server have DAT 6398 but it print that have the last update (March)...
Without knowing what the report defines as "in compliance" and what is "out of compliance" about these clients this will be hard to answer.
Edit the report and on the "Chart" tab click the "Configure Criteria" button. This will show you what is defined as in compliance or out of compliance. Then look at the client machines being reported as out of compliance and see what specifically is out of compliance about them (do they have the wrong version of VSE? do they have an out of date DAT file? etc).
