 I have found that the best modification to make is to add an entry in the registry that creates a receive window size of 64240. Others recommend that you change a whole host of other settings but I believe these to be
largely questionable, and at the worst - a hard to undo operation.
To install this modification, Right-Click on this file WindowsNT2000XP-64240 RWIN.reg and select 'Open' Select 'Open' again and then select 'Yes' and then 'OK' and than re-boot your system at your convenience. The specific changes that are made to the registry are listed below. It adds the TcpWindowSize entry to the registry and sets a value of faf0 (64240). It also adds the Tcp1323Opts entry and sets it to 0. Neither of these entries exist in the unmodified operating system. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\ HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\ To return your Windows 2000 computer back to the original settings Save This File to your desktop and than right-click on it and select install. This will remove both of the entries and it will be as if you never changed it - once you've re-booted your machine. Optional Knowledge
