Make VMware Virtual NICs part of an "identified network" to avoid firewall issues on running VMs

Make VMware Virtual NICs part of an "identified network" to avoid firewall issues on running VMs


When you add VMware workstation or viewer to a Windows 7 machine you will notice that this causes extra information to be carried in the "bubble" that appears when you over over the network icon.

You can make the extra virtual network cards part of an "identified network" to avoid this issue.



Follow the below:

  • Click Start, click Run, type regedit, and then click OK.
  • Click the following subkey: HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}
  • Browse through the 00xx subkeys until you find the REG_SZ VMNet subkey with a value of either “\DosDevices\VMnet8” or “\DosDevices\VMnet1” (default values)
  • On the Edit menu, point to New, and then click DWORD Value.
  • Type *NdisDeviceType, and then press Enter.
  • On the Edit menu, click Modify.
  • Type 1, and then click OK.
  • Exit Registry Editor.
  • Disable & re-enable the VMWare NICs
  • Done
Note: In case simply disabling and re-enabling the virtual NICs doesn’t fix the problem immediately reboot your computer.

The above needs to be put into a policy to apply to all Win 7 machines
