comment Network Routing through a Server to a NAS device
Walk up and down your colo and look carefully at the back of every other tenants' racks. Tell me what percentage of them have more than one server and don't have a switch. I'll bet it's 0%

comment In-place upgrade Windows Server 2012 to Windows Server 2012 R2 with System Center and SQL Server products installed
@Massimo that's not always feasible. Take my 8 server load-balanced and clustered System Center Service Manager infrastructure, for example. No way is it worth it to forklift to 2012 R2. That said, I have had great success in in-place upgrading the host OS for every System Center product from 2012 to 2012 R2.

comment Windows Server 2012 R2 DC promotion fails
And my point is that 2008 R2 and 2012 R2 to not behave identically and can't be assumed to.

comment Windows Server 2012 R2 DC promotion fails
-1 is not a valid functional level. If I had to guess, replication fails/times out which causes unexpected behavior due to contention over this slow link. After the initial sync, the amount of data needing to be replicated is tiny, which would explain why your other DCs are fine. Not saying that I know that this is definitely what's happening, but it's an easy avenue to explore.

This was my thought as well. It's typically labeled as "Memory Mirroring"

comment Migration of Virtual DC to another ESXI host
@SyedJahanzaib sounds like you don't have server or client DNS settings configured properly. Also, there is no "Primary" or "Secondary" DC - they are multimaster peers.

comment Lync 2013 VPN access
If your VPN users do not split-tunnel and appear as normal internal users and normal internal access is working properly, why would you need an edge pool? What issues have you encountered when you tried to pilot this?
