89. Fix large file copying
problems in Windows Vista
Out of the box Vista can have some issues with large file
transfers over a network. This is because of a new Vista feature called 'receive
window auto-tuning'. In a nutshell, this allows Vista to automatically scale the
size of each packet of data it requests and receives over a network connection
to suit the available bandwidth. This is a good thing. However, older networking
hardware may have issues with this newfangled technique and refuse to
co-operate, leading to dropped file transfers, slow performance and other
If you are experiencing network issues with large file
transfers and occasional connection problems with applications like Messenger,
we recommend that you restrict or disable the receive window auto-tuning
To do this, open a command prompt window with
administrative privileges (see Tip #20).
Type 'netsh interface tcp set global
autotuninglevel=restricted' and press Enter.
If this fixes your issues, relax. If you continue to have
networking problems, open another administrative prompt and type 'netsh
interface tcp set global autotuninglevel=disabled'.
Disable IPV6 in Windows Vista
Windows Vista is the first Microsoft operating system to

running both IPV6 and standard TCP/IP by default, wouldn't it be a good idea to
disable the unnecessary protocol? We think so.
To disable IPV6 in Windows
Start Regedit and navigate to
Right click on an empty area of the right-hand pane and
choose 'new\DWORD value'.
Name the DWORD 'DisabledComponents' and give it the value

impatient to wait for the screen to refresh itself. Fortunately, hitting the F5
key will refresh the screen automatically.
