Logon Scripts, Group Policy Preferences, and Server 2003 Migration: Part 1
Logon scripts are the bane of many server administrators. The group policy preferences feature that debuted in Windows Server 2008 can help you reduce or eliminate them.
IPAM managed DHCP server requirements
In the last post we discussed IPAM http://windowsitpro.com/windows-server-2003-end-support/understanding-ipam, a technology that allows you to centralize the management of your organization’s DHCP server. It’s important to realize that you are not limited to using IPAM to manage DHCP servers running Windows Server 2012 and Windows Server 2012 R2.
Understanding IPAM
When planning the migration of your DHCP infrastructure to Windows Server 2012 R2, you should also consider adopting centralized DHCP management through IPAM.
Migrating DHCP from Server 2003 to Server 2012 R2
Once you’ve ensured that you’ve documented your existing DHCP server configuration, you can migrate the DHCP server database from a Windows Server 2003 host to Windows Server 2012 R2.
Assessing Windows Server 2003 DHCP Deployment
Prior to migrating your DHCP servers from Windows Server 2003 to Windows Server 2012 R2, you’ll need to get a good idea of what your DHCP deployment looks like. Just so that you can be sure that you don’t miss anything.
Windows Server 2003: Post DNS Migration considerations
You’ve migrated all your zones from DNS servers running Windows Server 2003 to DNS servers running Windows Server 2012 R2. What do you need to do next?
Migrating DNS from Server 2003 to Server 2012 R2
Once you've completed the assessment of your organization's DNS deployment, it's time to migrate the DNS role from computers running Server 2003 to computers running Windows Server 2012 R2.
Assessing 2003 DNS infrastructure prior to migration
Prior to migrating from Server 2003 to Server 2012 R2, you’ll need to figure out which servers in your organization are functioning as DNS servers. You’ll also have to figure out which DNS zones are hosted on your DNS servers and the nature of those zones.
Migrating Server 2003 File Server Workloads
Migrating a file server workload from Server 2003 to Server 2012 R2 requires a bit more than simply copying the files from the computer running Server 2003 to the computer running Server 2012 R2.
Understanding new file server options
If you’ve kept your file servers running Windows Server 2003, you probably aren’t fully aware of the options that have become available in more recent versions of the Windows Server operating system.
Triaging File Server Workloads
Perhaps the most common Windows Server role is that of the humble file server.
Windows Server 2003 Migrations: Upgrading Domain & Forest Functional Levels
Once you’ve removed all of the Windows Server 2003 domain controllers from your environment, you can upgrade the domain and the forest functional levels.
Removing legacy domain controllers 2
Once you’ve added a sufficient number of Windows Server 2012 R2 domain controllers to your organization’s Active Directory forest, migrated the FSMO roles, ensured any custom partitions are also hosted on your Server 2012 R2 domain controllers, and made a couple of those 2012 R2 DCs global catalog servers, you can get rid of the existing Server 2003 DCs.
Moving FSMO Roles 1
One of the advantages of moving Active Directory from Windows Server 2003 to Windows Server 2012 R2 is that you get to take advantage of all the new Windows PowerShell cmdlets.
Introducing new 2012 R2 domain controllers to a 2003 environment 1
Introducing new domain controllers running Windows Server 2012 R2 to a Windows Server 2003 environment is relatively straightforward.

Looking forward to seeing features like JIT administration - something that we won't be able to play with until we can run a domain at the vNext functional level.
