Patch your TCPIP.sys file.
If you don't know what this, don't worry. Double-click the program and press C on your keyboard. Then just type in 50. Press Enter. Press Y. Now the program will check to make sure that the patch was applied properly. If you get any annoying Windows messages telling you that critical system files have been modified and need to be replaced with the original versions, just click on Cancel to prevent Windows from undoing what we just did. Reboot your system when the patching is complete. You can use higher values than 50, but generally you shouldn't need to. Sometimes this patch gets reverted by Windows patches, so if you find your connections timing out or getting weird network errors, check to see if your tcpip.sys is still patched!
