License Manager for Enterprise Networks

Is there a still a License Manager available for enterprise customers to run on their own networks?

All links I've found on the Adobe site so far are 7 years out of date, keep making more sales pitches, or take me to a web-based serivce. We already bought our licenses and web-based access is not an option because we conduct much of our business on isolated networks with no access to the internet.

We have nearly 500 users with a mix of Reader and other products licensed for individal users. Our network and software administrators are constantly installing and uninstalling products one at a time to keep up with all personnel and job changes. Anything that makes it easier for us to add and reassign product licenses would be a big help.
