Hyper-V Guest OS loses connectivity.

I've installed over 3 servers with some variation of the following as the symptom/remedy:


1. Install a fresh install of Windows 2008R2.
2. Install Hyper-V.
3. Install Virtual Machine - 2008R2
4. Install DNS, DHCP, File Services, and WSUS roles

Run Windows update on host machine as well as Virtual Machine.

No internet results on host machine.

Remedies:
1. Give the NIC assigned to the VM a static address.
2. Disable ipV6 wherever possible.

Now, unfortunately, in my latest install, I did both of the above, and nothing...

Funny part, I can ping the VM, but the VM cannot ping out.  If I enable v6, it can ping other v6 machines on the network.
 
Ideas?

Make sure the vswitch you're using has a gateway configured... can you ping the gateway from the vm?

Turns out the phone system was on DHCP and gave itself my server's IP while I was physically moving it!  Changed the server's IP and all looks well.
