Two things happened to me today when I tried setting up Microsoft Virtual PC 2007 on my Windows 7 x64 development machine. First I received an error saying "Virtual PC could not open the virtual machine network services driver." To solve this problem I had to go into the network adapter properties of the host machine and enable "Virtual Machine Network Services." Here is a picture of the network adapter property you want to have checked.

I found the solution to this problem at http://www.aspdeveloper.net

After the network service error was gone I then received an error when starting the virtual machine. The error said "The network adapter with address "00:00:00:00:00:00" of virtual machine 'VMName' failed to initialize because the address is a null address." To fix this problem I had to edit the registry by using regedit. Here are the steps:
1. Examine the key value at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\nnnn\DriverDesc to locate the desired host adapter where nnnn is a four digit number.
2. Look at the GUID value for the NetCfgInstanceId key value.
3. Add the DWORD key named "Flags" at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VPCNetS2\Parameters\Adapters\"guid" and set the value to 0 where "guid" is the GUID found in step 2.
4. Restart the computer.
