Hello,

Some info about my current setup:

windows Server 2012 running on the host machine.
Installed Hyper-V and RDS.

Inside Hyper-V i have a Domain controller with DHCP and DNS.
DHCP has scopes configured to go between 10.1.1.30 - 10.1.1.240

I am running from a Home router with no static IP (am using dynamic DNS instead)

I have DHCP enabled on my router, however when I disabled it and try to use DHCP from the DC VM, it will not work. I also lose internet connectivity on the host and VM's

I don't really have much networking experience, and after spending two weeks trying to figure this out, I am just wondering if someone with more networking nous can give me a hand.

Well, to be honest, the only reason I have installed DHCP and DNS on the server is because I am following a test lab from microsoft.

I am troubleshooting a bigger problem which is that a the RDVH cannot communicate with the VM to acknowledge a sysprep and bootup.

First stop is networking related issues, hence this question.

FYI - The purpose of the server is to POC remote desktop virtualisation.

how is your Virtual Switch setup in Hyper-V Manager?

When I add the the Hyper-V add on, I select the only NIC installed and create a virtual switch with the install wizard.

I then install RDS on the host and select "Create virtual switch on Virtualisation host" - According to forums, this should then install a switch called RDS but nothing appears for me.

I also create an internal switch and add this to all VM's that I create, so all VM's will have the Virtual switch created by Hyper-V as well as an internal switch.

Hi Nathan, I appreciate your input.

http://technet.microsoft.com/en-us/library/hh831541.aspx

You'll notice at the end of the document there are two users who didn't have a RDS virtual switch created either

I have no idea if this is related to my problem, it is only a guess.

freitasm: Any reason why not let the router perform the roles of DHCP and DNS?


Active Directory needs to be a DNS, or needs thing that a consumer class router doesn't support like CNAME and SRV records

so DHCP is configured on the server?  and the Server VM is attached to a Hyper External switch bound to a physical NIC

and other machines on the LAN or VMs on the same external switch won't get an address?

The DHCP role is installed on the same VM machine as DC and DNS (which has two switches 1 is attached to the external virtual switch bound to a physical NIC. 2 is the internal switch)

The LAN machines and VM's are getting IPs, but if I check my address leases on DHCP nothing is appearing, nor are the IPs within the desired scopes which I've created. So, it appears 1) They are getting IPs from my router not my DHCP VM; the same problem persists even after disabling DHCP on the router.

is it bound to the correct NIC

if you put a VM on the private/internal VM switch does it get a lease?
