You might have to call McAfee and give them your grant number, they should be able to provide you with the package to import into your master repository.
Are you running ePO 5+? If so you need a minimum of MA 4.8
I will be running ePO 4.6.6. The only reason I am looking for agent package 4 is to work with the few Windows 2000 machines I still have on my network. everything else will be agent 4.6 or higher.
Moved this to ePO as a better spot.
I know MA 4.0 patch 3 worked with ePO 4.5; but I do not know if ePO 4.6.6 supports MA 4.0. Your best bet is to call McAfee - they can give you MA 4.0 and let you know if it works on 4.6
ePO4.6 supports the agent 126.96.36.1994 (The one your after for W2k Machines) as I have this on one of my customer sites.
The agent should still be available from the download site via your grant number, or failing that contact support & ask them for a copy but Stress you need it for W2K machines only.
