Hi Ray,
1. Do I just install the ADNM on a server and it will take care of installing the server/workstation versions onto the other machines?
ADNM server is basically just a front-end to a MS SQL database that holds information about the “A/V state” of all servers and workstations on your network. I’m sure you already knew that though.
It will be the application that you use to distribute avast to all other machines on the network. It basically controls almost every aspect that pertains to avast on every client on your network. From scheduling, configuration, installation, removal, etc.
How resource hungry is ADNM/Server Ed? Is it advisable to run it on the server with Exchange? Or safer to put it on one of the others?
As for resources, as I explained before, it is a front-end to a SQL database. Although it doesn’t use many processor cycles, it may run your memory usage up a bit. For 20 workstations and 4 servers though, I wouldn’t call it “resource-hungry”. You can probably install it on your backup server, or your SQL server and as long as it has about 4GB of RAM, I don’t think you’ll notice a darn thing.
3. Is install & configuration pretty straight forward, or do I need to plan for a few days to get it up & running?
Well, experience is worth more than anything, as most things in I.T., but I’d have to say that it’s pretty easy (I install in just an hour or two, usually). Especially since your environment is so small. You’ll install the ADNM server, get the license file and import it, create some deploy tasks (one for workstations, one for servers, for example), configure settings for your computer group, then schedule some update / reporting tasks (update virus definitions everyday at so and so time, then update the full program once a week on Monday mornings at 6 or something like that).
Once that’s done, you can do a discovery task (which finds what computers are on your network), then deploy avast to all of them. After that, you’re pretty much done.
The ADNM manual will be a good help in starting this. It’s available on this page: http://avast.com/eng/download-adnm.html

All in all, it will take a bit to get used to, just like starting to use any program, but it’s pretty simple once you get used to it.
