Chapter 1
Enterprise Mobility and MDM Essentials
In this first chapter, weâll get to know what MDM is, where it came from, and how itâs different than its cousin Group Policy.
I think the best place to start is right at the top of a new page. Like this one.
And thatâs kind of what Microsoft did when they decided to dedicate their efforts with EMM and MDM and not continue down the path of investing more features into existing core on-prem Active Directory and Group Policy technologies.
Again, as I stated in the bookâs Introduction, Group Policy is not dead. And Microsoft has not âturned offâ Group Policy usage for on-prem scenarios, nor should you live in fear that your favorite new, âWindows 10 gismo,â will lose the ability to be controlled by Group Policy.
But, going forward, you can expect that nearly all Windows 10 (and related settings like Edge) should be controllable with either Group Policy or MDM. There are some exceptions, but Microsoft is committed to adding new settings to GPO. That said, donât expect new major Group Policy features (like enhanced Group Policy reporting new Group Policy Preferences, or additional troubleshooting tools). But do expect more Group Policy settings to be born each and every time Windows 10 ships, and youâll see these as the Group Policy Admin Template policy settings (ADMX settings) youâve come to know and love for umpteen years.
For new Group Policy features, like managing the Start Screen and Taskbar and File Associations, while there is some rudimentary stuff in the box, I heartily suggest you take a look at PolicyPak Group Policy edition, which will supplement the missing features most on-prem AD admins are looking for.
The reality is that the concept of Enterprise Mobility and thus using MDM to manage Windows is Microsoftâs new focus, and itâs not looking backward to bolster core Group Policy functions anymore. But at the same time, it is also not killing Group Policy either for use with your existing domain-joined machines.
Microsoft is expecting you to keep using traditional management like Group Policy for some scenarios and modern management with MDM for other scenarios.
Getting Ready to Use This Book
To go through some of the exercises in this book, you will need to own or get evaluations of some software. Or not, and just read the book and see the pictures and get a general feel for what would be involved.
You donât have to do this now, but to take advantage of the walk-throughs in this book, you will be acquiring the following:
- Azure AD (free) or Azure AD Premium (preferred for this book). And, if you have Office 365, you already have Azure AD.
- An MDM service, like Microsoft Intune, VMware Workspace ONE, or MobileIron. Most of the main services have 30 day (or longer) evaluations.
Again: Donât do this step now; weâll tackle that in the next chapter.
If you did want to follow along with all the ideas Iâll be showing, you can take some time now to have some representative on-prem infrastructure to simulate what you might already have now. So if you donât already have a test lab you can beat up, hereâs my recommendation of the following computer names, with the following operating systems:
- DC01 (I recommend Server 2019 or Server 2016.)
WIN10Computer.fabrikam.com joined to DC01. If you have other machines joined to Fabrikam.com too, that would be okay and likely useful as well. - WIN10-NDJ-1 not domain joined at all
- WIN10-NDJ-2 also not domain joined at all
You might need more as we go along, but these are a good start.
I suggest you use VMware Workstation or Hyper-V on Windows 10 to make a simulated lab environment. That being said, fair warning, some of the scenarios in Chapter 8, âRollouts and Refreshed with Configuration Designer and AutoPilot,â wonât work unless you have real hardware. Iâll call those scenarios out when the time comes.
Iâm not going to provide any step-by-step instructions for you to bring up your own domain and Domain Controller. But one of my PolicyPak teammates created a video on how to do it here if youâre unfamiliar:
Then join at least Win10Computer to the domain you create; in my examples, Iâll be using the domain name Fabrikam.com.
You might want to have a small gaggle of on-prem AD users pre-created in an OU called Sales. Name your test users anything you like, but youâll see mine in the book like EastSalesUser1, WestSalesUser7, and so on.
Additionally, as I go along, you might see me manually create other users (in on-prem AD and in Azure AD).

Why the Need for MDM
Throughout the years, I kept hearing the supposed death knell of Group Policy. But, itâs more than 19 years since Windows 2000, and, well, itâs still here, and seems pretty darned popular.
So much so that I went a little bananas in 2016 and 2017 and wrote a blog post called âThe âWhy Group Policy is Not Deadâ Manifesto.â I mentioned this in the bookâs introduction, but if you didnât read it then, take a moment to read it now. It can be found by moseying over to MDMandGpanswers.com at:
I highly recommend you take a moment and read it and then come back here to continue. Itâs long, so maybe it takes two moments.
So, if Group Policy is so great, then why do we need MDM as something to look to for the future? Because as I said in the introduction, Group Policy cannot be the only transport if we want to solve for new scenarios and use cases.
Because in some ways the future is already here. Here are the key factors I see why people are looking at MDM:
New Workstyle: Constantly on the Go You have one. A cell phone. And itâs âconstantly on the go.â In fact those are literally the words that Microsoft uses when it explains its position of the benefits of MDM. And yes, cell phones are the primary device thatâs always on the go, but we can all agree that carrying around your laptop is easier than ever.
Note that you can see some of Microsoftâs position with regard to MDM if you read this blog entry called âManaging Windows 10 in your organization - transition to modern management.â Itâs found at:
New World: Internet Everywhere If not everywhere, pretty darn close to everywhere. There are always going to be third-world countries and submarines and dead spots. And broken Wi-Fi hot spots. But the prospect of LTE and 4G and (coming soon)...
