What might make management change it’s mind about migrating from Windows Server 2003?
Almost every server administrator who is still responsible for managing Windows Server 2003 is doing so because management won’t provide the resources to migrate. What might make management change its mind?
Why an unsupported operating system might not be your most pressing problem 2
There is no doubt that running Windows Server 2003, a 13 year old unsupported operating system, is problematic. For many organizations, however, there are bigger problems to deal with than an unsupported operating system that still does its job.
When IT wants to migrate from Server 2003 but management ignores them 3
I haven’t met an IT Pro who is happy that Windows Server 2003 is still in their environment. When I ask why it is still there then, they reply that management doesn’t want to provide the resources to make it go away.
Why Azure AD isn’t a cloud domain controller 2

There is some confusion as to what Azure AD can and cannot do and whether it could function as a cloud based domain controller.

Do you need on-premises central sign-on?
When determining whether to decommission or upgrade your Server 2003 Domain Controllers, the question you need to answer is whether you need on-premises central sign on.
Do small organizations still need domain controllers?
When considering a migration from Server 2003 to Server 2012 R2, organizations should determine whether or not they still need on-premises domain controllers.
Samba as an alternative file server
The most common role for a server running the Windows Server 2003 operating system is file server. Should you not be interested in upgrading your file servers to Windows Server 2012 R2, you could consider the possibility of migrating your file servers to Samba on Linux.
Replacing Server 2003 with Linux alternatives
For some organizations that use only a small subset of Windows Server 2003’s features and who have appropriately trained systems administrators, it may make sense to migrate some servers to Linux rather than to a newer version of Windows Server
Alternatives when upgrading from Server 2003
For most people, migrating away from Server 2003 means migrating to a newer version of Windows Server. Rather than upgrading to Server 2012 R2, some organizations might consider looking into alternatives such as another OS or hardware appliances.
Running Server 2003 is not a long term proposition
It’s not really a surprise that a significant number of organizations are still running Server 2003. What all of them must realize at some point is that Running Server 2003 is not a long term proposition. At some point in time those servers are going to need to be decommissioned. The sooner the better.
You’re going to need a plan to get yourself off Server 2003
No matter how much you might wish them to simply disappear, the only way that you’re going to get your Server 2003 servers out of your environment is by coming up and enacting a plan.
You can run Server 2003 and be supported, but it will cost you
Microsoft is willing to still support Server 2003 and provide you with software updates for the operating system. But there are some catches.
Organizations will be running Server 2003 12 months from now.
I just got back from delivering sessions at Ignite New Zealand. During each session I polled the audience to learn how many were still running Server 2003 in some capacity in their organization. Each time I asked roughly 30-40% of the room put their hand up.
Many organizations still don’t have a Server 2003 migration plan
It may shock you, even surprise you, but a large number of organizations that are still on Windows Server 2003 after end of support for the operating system expired still don’t have any firm plans on how and when they will migrate to a supported version of the OS.
Reports of Windows Server 2003’s death have been greatly exaggerated
The uncomfortable truth is that a large number of computers running Windows Server, many millions in fact, are still humming away in server rooms and datacenters more than a month after support for the operating system expired.

Windows Server 2003 EOL’s Y2K Problem
March 11, 2015

I did months of running around as well checking computers for possible faults, running tests, the whole bit.

But the perception was that Y2K was a fizzer.
