"If you simply do not want your system to automatically enable the DF bit in
outgoing TCP/IP packets this feature can be entirely disabled through the
registry. Changing this value will adversely affect WAN communications from
the Windows host, however, because the MTU for all communications that must
be forwarded through a router is automatically set to 576-about one-third of
the most common network MTU. Disabling this feature does not afect LAN
communications - the default is alwayss used. The registry value to add is:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Enable
PMTUDiscovery (REG_DWORD)

Setting the value of this registry entry to 0 disables the automatic path
MTU feature of Windows as described in the preceding paragraph."
