Checking replication of raising the Domain Functional Level to Windows Server 2008 in a pragmatic and programmatic way

I’ve referred to the Windows Server 2003 Domain Functional Level (DFL) as the ‘golden’ functional level a couple of times. Dave has a blogpost where he concludes the same from an Exchange Server point of view. However, from an Active Directory point of view, the Windows Server 2008 Domain Functional Level (DFL) gains much traction […]

In these environments, mobility over several devices, for instance a desktop and a laptop, often, […]


I’m still an ADPrep kinda guy

In Windows Server 2012, Microsoft introduced the new streamlined Active Directory Domain Services Configuration Wizard, that in most Microsoft documentation is labeled the successor to dcpromo.exe. I’m a big fan of the new wizard, but there’s one feature I don’t use: the automatic Active Directory preparation steps it can perform for you to update the […]
