Very much appreciate all the feedback. To answer a few questions:
-We were eligible for an upgrade to SAV 10.2, so this was surely the most cost effective route for us.
-Our lowest hardware spec is an XP machine with 512RAM and I believe ~1.8GHz proc.
We definitely can't use a program that is very taxing on the machines. On the flip side, we will be slowly introducing Windows 7 machines into the environment and want to make sure this program would be compatible for that as well.
Getting us into 2012 without having to buy software would be nice. We're a state agency and it's not the easiest thing to purchase software.
On the other side of the coin, we are looking to upgrade our Antivirus on another set of computers that are more local to our environment. These machines have a wide array of specs, but most are XP or greater. We are looking for a program that can centrally manage computers that are local to our network.
If we can combine both solutions into one, we may be able to purchase some nice software. I would love to hear some recommendations for that -- software that can manage local and remote machines and monitor updates.
Overall, if we're able to combine a solution for both environments, we would be looking at around 100-150 licenses needed.
Thanks for all the help so far, and I look forward to hearing some recommendations.
