I have a VM set up in Hyper-V and 2 virtual switches that SHOULD allow me to RDP to the VM and for the VM to have access to the internet. I can RDP to the VM, but the VM does NOT have access to the internet. I have it configured as follows. Can anyone see my problem? I thought I had this setup working before:

Hyper-V Switches:

Internal Switch External Switch

VM Adapter Settings VM Adapter Settings - Internal VM Adapter Settings - External

Host Adapter Settings Host - Internal Switch Adapter Config Host - External Switch Adapter Config

Guest Adapter Settings Guest - Internal Switch Adapter Config Guest - External Switch Adapter Config

Does the guest VM external NIC have a valid ip address and default gateway? Is the guest VM running DNS server software? – joeqwerty May 10 '13 at 0:56
The Guest VM is running Server 2008R2 and is a Domain Controller. The last image in the list is the Guest External Adapter, and it gets its address automatically. Is there a test I should to do see if it's getting a valid IP? – Andrew B Schultz May 10 '13 at 1:03
1. It's not recommended that a DC/DNS server have a DHCP asigned ip address. 2. You can run ipconfig/all from a command prompt on the DC to see if it has a valid ip address and default gateway. – joeqwerty May 10 '13 at 1:48
Thanks for the info. My setup is working now ... I think I had to reboot or something before the settings started to take hold. – Andrew B Schultz May 14 '13 at 22:53

Just started working. I think these settings are OK, but there was something else going on that made it so my VM couldn't connect to the internet. After a few days (and several restarts) I checked again, everything was working.
