ADMS is required if you are using Vault, Content Center, or any applications
that depend on Content Center (bolted connection, tube & pipe, frame
generator, etc).
However, ADMS does not need to be installed on every machine.
For Vault I don't think it makes sense to have ADMS installed on each
machine; but for Content Center some people like to have everything on their
machine so that they can still do everything while disconnected from the
network. Vault users can do things like a pack-and-go to get everything they
need before they disconnect from the network.
Hope this helps,
