Time to put it into the lab until service pack 1 is released...um, wait.
Seriously, I cannot deploy this version with most of my known AD environments because:
- Replication of AD integrated DNS zones not fully supported
- DFSR not supported, NTFRS and DFS are not good enough
- The fact that I cannot have a single operating system standard for the forest/domain which governs all security, audit, and governance policies. In short, it makes AD more complex
The only advantageous deployments I can clearly understand are for a resource forest/domain where all servers in the domain are not Windows. Why? Because as soon as you add a single Microsoft Windows server which authenticates users you are required to purchase Windows Client Access Licenses for each real person or an Internet connector license.
So unless I am replacing all of the Windows servers with linux, I am not saving any money, only making the environment more complex to manage.
