Avoid network problems due to bad network identification on both VMWare virtual adaptors


This small tip will help you to solve sharing troubles, or network issues that appear after installing vmware on your computer.

In my case, I have Serviio installed (which is a great multimedia server that I connected into my TV). Just after installing VMware, that software stopped working. That was solved just after disconnecting both virtual VMWare NIC cards.

As I don't want to reset the computer each time I want to activate a virtual machine, I've searched the Internet until a solution appeared.

I'd like to thank Patrick Moore (


You will need to know how to modify the Windows registry...

Following the Steps

You will have to follow those steps:

  1. Open Windows registry ==> Win+R ==> REGEDIT
  2. Navigate to this key: HKLM\System\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
  3. Navigate through the folders inside the previous key until you'll find an entry called "VMNet". (There will be one for each virtual NIC). You can also search for that entry using the find commands in the Edit menu.
  4. Add a new DWORD 32 bits value and name it *NdisDeviceType. Don't forget the * as it is needed.
  5. Set its value to 1.
  6. Repeat steps 3 to 5 until both NICs are updated.
  7. Close regedit.
  8. Disable and reenable both NICs.
