My main purpose is to provide SQL Server Analysis Services (SSAS) on a single physical machine running on say cloud provider premises. Just a remote box that should be accessible worldwide through VPN.
Since SSAS uses only Windows authentication and there will be several dozens of users connected to it I need Active Directory Domain Services running. As we know Windows Server 2012 Standard license lets us run up to two virtualized server. Thus now I have one physical WS 2012 R2 with Hyper-V and RRAS roles installed and one virtual WS 2012 R2 with AD DS, DNS and DHCP roles. Both servers are connected to internal network Hyper-V virtual switch with static IPv4 addresses 192.168.1.1 and 192.168.1.2 correspondingly. And everything works fine at the moment. I would like it keep working the same way all the time :)
But I wonder if it's possible to use DHCP reservations (please remember DHCP server starts after a physical machine since it's on virtual machine!) to get rid of static IP addressing and if so does it make any sense and advantages.
