Better still... offer this as a .reg file:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters]
"DisabledComponents"=dword:ffffffff
And if you have "port security" on your network switches that limits the number of MACs
on a port, add these:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LLTD]
"EnableLLTDIO"=dword:0
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LLTD]
"EnableRespndr"=dword:0
