ePO is not licensed separately to my knowledge. If you brought licenses for VirusScan Enterprise then ePO comes free with it. You should be able to download this using your Grant number from the downloads page. http://www.mcafee.com/us/downloads/downloads.aspx
To answer your question, when you install VirusScan manually, it does install Frameworkservice but does not report to ePO (unmanaged). You can make existing unmanaged clients managed by either pushing the Agent from ePO or alternatively copying the sitelist.xml, srpubkey.bin, reqseckey.bin files from the ePO master repository (DB\Software\Current\EPOAGENT3000\Install\0409 folder) and updating the sitelist of each system manually like so:
frminst.exe /INSTALL=AGENT /Siteinfo=C:\Sitelist.xml
Ensure that srpubkey.bin and reqseckey.bin files are present in the same folder as sitelist.xml (in this e.g. C:\) on the client machine before trying to update the sitelist.xml file. This should allow the client to report back to ePO.
Also, you should be able to convert the trial ePO license to full version by entering the actual license key on the ePO login screen. Your license key should be visible as soon as you login with your Grant number on the downloads page.
thank you for your responce. it was helpfull.
one quick question, is there anyway in ePO to kinda auto discover the clients on the network and register 'em in ePO?
Yes, please lookup Rogue System Detection in the Product Guide. You will need to deploy at least one Agent in each subnet and then deploy the RSD Sensors on those machines. Once the Sensors are installed, they will sniff the network traffic and report back to ePO. You can configure Automatic Response to push agents to those detected systems (Rogues) and make them managed.
