APPLIES TO:
  • Parallels Desktop for Mac
  • Parallels Workstation 4.x Extreme

Symptoms

There is no networking in a virtual machine. In Windows Device Manager you can see network adapters working improperly (marked with red or yellow signs). Any attempts to delete them results in error:

"Failed to uninstall the device. The device may be required to boot up the computer"

Resolution

Click on Windows Start menu and hit "Run...". This will open a window.
Type "regedit" (without quotes) in the window prompt and hit Return.
On the left pane of the screen appeared navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}

key and find in sub-directory a list of all network adapters. Check if there are any adapters with "Characteristics" value 0x00000029(41).
Change the value to 0x00000001(1) by double-clicking on "Characteristics" and typing 1 in the "Value data" line showed up.

After that try to delete broken network adapters again, restart the virtual machine and reinstall Parallels Tools.
