Ok i am baffled, for this worked.  I have a Win2k8 r2 server running
DHCP, AD, DNS, HYPER V
I have 3 nics 2 physical one virtual for Hyper V
Nic 1  IP 192.168.111.7 255.255.255.0 gw 192.168.111.1 dns 192.168.111.7
Nic 2 DHCP (Hyper V to use this Nic)
Virtual IP 192.168.111.17 255.255.255.0 GW 192.168.111.1 DNS 192.168.111.7


Hyper V uses Nic 2 and has 3 servers in it with static ip 192.168.111.19,18,178
All HyperV Servers can hit the Internet Fine ping outside etc..

The main server can not ping out side.  Was working fine,  DHCP and DNS are bound to .7 Nic
Everybody was hitting the internet that used 7 as DNS then it just stopped.  I had to put a forwarder to another internal DNS so they could resolve.  Has do something with main box not being able to get outside. the wierd part all the Hyper V's can get out side.  The order of service for Nics are Nic 1, Nic 2, Nic 3

Did no updates etc,  DHCP is working its handing out addresses

Any suggestions?

Why does the host have 2 physical NICs running with 2 addresses? Since you have a domain controller, it should use 1 NIC with 1 IP. The second NIC should be connected to the virtual network for your VMs only, and it should not be sharing it with the management operating system. NIC 3 should be unused and unplugged.

If you do 'ipconfig' from the host you should only see 1 valid IPv4 address.

I am little confused. but its monday.  The 2 nd nic is tied to the vm, but it will either have a static address or it pulls a DHCP (which it is doing, with static for the VM) should I assign a strange address?  Nic 3 Is a virtual nic that was created when I installed VM  How would I remove that.
thanks
