Do you have any sort of restrictions set up? Maybe something Windows Firewall related on the DC?

Hyper-V uses the concept of virtual switches, and much like the name implies, it is very similar to a physical switch. Just in software.  You have to create the switch. Give it a physical port to the outside world (usually a second or third or fourth NIC) that is connected directly or indirectly to a router. Then in each VM, attach a virtual NIC to the virtual switch. Just like plugging a physical machine into a switch with a patch cable.

Then from within the VM, you set up the IP settings on the virtual NIC just like you would a physical NIC.  Has to have an IP address (or use DHCP) and a proper subnet and gateway.

And I *really* hope you aren't running Hyper-V *on* your domain controller. If you are, please stop now and replan. This is not a good road to go down.

I have Windows Firewall enabled on the DC control. The Hyper-V actually runs on the the physical box and not on the DC. Everything is setup correctly and works fine. I just had an instance one Monday where I walked in and no one could get on the DC computer to access company information. I also notice no one could surf the web. When I tried surfing the web from one of the VM (DC for instance) I was not able to get a valid web page.

When I went back onto the main box I could navigate to the web. All I did was do a hard reboot on the server and once back up everything connected. I look in the event logs and could not find an error relating to the issue.
What type of NICs are in the server? You have to turn off VMQ if you have Broadcom NICs.

I will double check that!
