DHCP error while WinPhone8 emulator is starting

Question

I had a Windows 8 PC with a perfectly working WinPhone8 emulator.

A few days ago my OS broke and our IT guys reinstalled Windows 8 in identical configuration. I installed the WinPhone SDK and tried to run the emulator without success (with message similar to your Hyper-V isn't enabled although it was enabled).

After fully patching (I installed SDK before that), the emulator started but I got the error You don't have permission to modify internal hyper-v network adapter settings.

When I clicked Retry I got a message about a possible issue with the network, so I pressed OK and my PC crashed within a short time after the emulator initialized.

I added my user to Hyper-V Administrators but this also changed nothing (PC still crashing). I checked Event Viewer and found there next message.

Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0xE02A82E2702D. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

I googled about this issue and found the suggestion to turn off the Internet Protocol Version 6 (TCP/IPv6), but this didn't help.

Does anybody have any idea about how to fix it?

Answer 1

Your problem seems to be caused by the newer SDK that you are now using.

One possibility would be to go back to the older version that worked, but there is another solution described in the article : Troubleshooting Windows Phone 8 Emulator problems :

• Run the Hyper-V Manager, and click on the Virtual Switch Manager.
• If there is no entry resembling Windows Phone Emulator Internal Switch, click on New Virtual Switch, choose Internal and then Create Virtual Switch. Create a new entry called Windows Phone Emulator Internal Switch and then click on OK - this will create the emulator switch.
• Open the Network and Sharing Center by right clicking on your Network icon in the system tray or accessing it via the Control Panel. Then click on Change adapter settings. You will see a list of your network adapters, including the one we have just created.
• Right-click on the adapter, and select Properties.
• Untick all the items except for:
  • Client for Microsoft Networks
  • QoS Packet Scheduler
  • File and Printer Sharing for Microsoft Networks
  • Microsoft LLDP Protocol Driver
  • Link-Layer Topology Discovery Mapper I/O Driver
  • Link-Layer Topology Discovery Responder
  • Internet Protocol Version 6 (TCP/IPv6)
  • Internet Protocol Version 4 (TCP/IPv4)
• Click on OK.
• Reboot

You may need to disable your VMware adapters or you may not. If you still have problems, you can check what network adapter your emulator is using by running Hyper-V Manager. You can see the list of virtual machines running. Click on one of the emulators, and then at the bottom, click on the Networking tab, and you can see which network adapter your emulator is using.
