Microsoft Device Emulator allows emulation of Windows Mobile devices on a PC. When trying to setup a network connection to the internet, you may get this error:
Error: No VPC network adapters enumerated or no host network adapter with provided MAC address found.
To fix this, click File -> configure… -> Network, then tick Enable NE2000 PCMIA network adapter and bind to: then select a spare NIC to bind the network connection to. Save and restart the emulator.
