Windows Server 2012: DFSR information

Posted by bartvdw on 1919/1111/2012

Great article describing a lot of DFSR improvements in WS2012.

Beware in the ‘Dynamic Access Control Support’ part, it states: ‘Microsoft strongly discourages mixed Windows Server 2012 and legacy operating systems DFSR.’

In the comments the author Ned Pyle notes regarding migration: ‘Remember the point above that you should not deploy claims-based access/central access policy to these machines until you have all Win2012 though.’

I think that’s quiet important detail to remember! Now start reading these great articles, both by Ned Pyle…! 🙂
