Configuring Active Directory Deletion Protection
Migrating to Server 2012 R2 from Server 2003 brings with it the ability to leverage the benefits of the new operating system. One of the benefits of Server 2012 R2 that you might not know about is Active Directory Deletion Protection
Karl Popper and Technical Troubleshooting
Back in the 1930’s a philosopher named Karl Popper came up with the idea that scientists should attempt to falsify their hypotheses rather than to verify them. This is known as Falsification and it can be quite useful as a troubleshooting tool for IT Professionals
Migrating Windows Server 2003 Service Accounts to Group Managed Service Accounts
Ask Windows Server administrators about the security of their service accounts and many will start avoiding eye contact.
Retiring WINS after migrating from Windows Server 2003
I sometimes think that WINS will be the service that out lasts every other role available on Windows Server.
With less than 60 days to go, 135,000 instances of Windows Server 2003 still running in Australia.
According to a recent report in Computerworld, quoting data from Hewlett Packard’s South Pacific business, Australian businesses still have around 135,000 instances of Windows Server 2003 still in production.
Why don't some Server Admins like Server Core? 3
You’ve probably heard the saying “You can lead a horse to water, but you can’t make it drink.” Well that saying sort of applies to the Server Core installation option of Windows Server 2012 R2. Microsoft can provide a more secure version of an operating system that hosts the majority of everyday workloads and requires less rebooting, but it doesn’t mean that the majority of Windows Server Admins will actually deploy it.
Updating Password Policies When Migrating From 2003 to 2012 R2
An advantage of moving from Windows Server 2003 to Windows Server 2012 R2 is that it gives you the opportunity to implement different password policies. Password policies determine password complexity, password length, how often passwords must be change, how many passwords are remembered, and account lockout policies.
Server 2003 Migration and Group Policy Rationalization
Prior to migrating from Windows Server 2003 to Windows Server 2012 R2, you should perform some sort of audit to determine how many group policy objects your organization has, how group policy is applied, and whether or not it could be done in a more efficient manner.
Server Core: A better option when migrating from Server 2003
When migrating workloads from Windows Server 2003 to Windows Server 2012 R2, you can migrate the workload to a server running the Server Core installation option rather than the “full server” installation option. Even though it’s smart to go Server Core, many administrators migrate to full server. Here’s a couple of reasons why they should reconsider
Windows Server 2003 Migration: Restructuring OUs
Chances are that if you still haven’t got around to migrating from Windows Server 2003 to Windows Server 2012 R2, that the OU structure at your organization is pretty much the same as it was when you initially deployed Windows Server.
Locating Derelict Data
Prior to migrating file servers to Windows Server 2012 R2, you should perform a check to ensure that the servers aren’t still storing data that has exceeded its use by date.
Finding stale computer accounts
Stale computer accounts are accounts for computers that are stored within Active Directory where the computer hasn’t actually connected to Active Directory for a lengthy amount of time. planning a migration from Server 2003, one of the tasks you should perform is to clean up your organization’s Active Directory environment by removing these state computer accounts.
Locating users with non-expiring passwords
A bad habit of systems administrators is to configure accounts with non-expiring passwords. When you are upgrading from Server 2003, you’ve got an opportunity to do some spring cleaning, and that can involve finding all those accounts that are currently in the directory that are configured with non-expiring passwords.
Locating Derelict User Accounts
Prior to migrating from one version of Active Directory to another, you should perform some “spring cleaning”. This means performing a general tidy up, including removing derelict user accounts.
Challenges in supporting an obsolete server OS
After Windows Server 2003 reaches its end of extended support date on July 14 2015 it will, for most people, become a functionally obsolete operating system.

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.
