I had heard several times that Windows 2000 won’t join a Windows Server 2012 R2 Forest, especially in Windows Server 2012 R2 Functional Mode.
I did not find this to be the case. The hardest part was finding the old Windows 2000 MSDN CD in the basement (I ISO’ed it so I can lose it on my NAS now) and getting Windows 2000 Professional to load into a Windows Server 2012 R2 Hyper-V VM. Once I got past that point it joined the Active Directory with no issues. I even used the GUI without a pre-created machine account.
And to boot… Both the current version of AdFind and the current version of AdMod both worked fine on the Windows 2000 Professional SP4 machine… PowerShell AD Cmdlets didn’t seem to work though… 😉
