The MaxMTU Fix for Windows 95 only.

MTU is Maximum Transmission Unit. Different data protocols have different package sizes that cannot be exceeded. Knowledge of the MTU is required by TCP so that the package sizes can be optimised to prevent fragmentation during transmission across the internet. The Windows 95 default is 1500 which is the Ethernet standard MTU. The internet "standard" for MTU is 576 but many ISPs use MTU's greater than this. However, if you are connecting to a site on the other side of the world (or country) then your data may have to go through a router which has an MTU of 576. This would cause delays and retransmissions in your requested data if your MTU was greater than 576. The minimum permitted value is 68.
