Domain functionality levels
-
I found something curious in this post.
At the end of the OC video, the presenter has 1 DC (2012) but opts to only have 2008 domain functionality instead of 2012. I've been told by other sysadmins (offline) that they refuse to raise domain functionality to 2008 R2 (what their domain controllers are all on) instead of 2003 because it'll break all the old 2003 member servers/services across the network.
I say how completely false that is, and that domain functionality only pertains to functionality between the domain controllers.
Am I misinforming people in saying domain functionality should be 2008 R2 with all 2008 R2 DCs? If I'm not misinforming, very curious why the video presenter didn't raise the functionality further...

I have seen SMB version problems, but nothing that I know of that pertains to Function Level causing issues.
-
I know that Samba4 cross compatibility requires no higher than 2008R2.
-
Function level has no effect on memeber servers, it has to do with replication and directory schema. we are on 2012 R2 Domain Functional level, 2008 R2 Forest Functional Level.

SMB versions are based on OS version if you have a 2012 Member server even on 2003 functional level it can still be doing SMB v3

I couldn't save to a Windows 2012 server from Windows 7 without changing the security level that 2012 was using, I think it dropped 2012 from using SMB v4 to v3, but that specifcs I could be wrong about.

There isn't a SMB v4..

SMB 3.1 is the latest, I believe.
