One of the biggest complaints that I have with Vista, is that compared to Windows XP, browsing File Shares is often painfully slow. Here's how to speed it up.
Open up a command prompt in administrator mode. To do this, click Start, type "cmd" and hold down Control and Shift on your keyboard and hit Enter. If you have User Account Control running you'll need to click continue. Now you should see a command window open with the word "Administrator" in the title bar.
Now enter in this command.
netsh interface tcp set global autotuninglevel=disabled
You'll need to reboot your system, but you should now find that browsing remote file shares is much, much quicker.
