bryanOkay, I've been pulling my hair out for the last three days as Remote Desktop is running very slow and timing out on my Vista machine, calls to the host provided and BT have not solved the issue.
Found out this morning that remote desktop works fine on my XP machine, so it must be something Vista is doing. After a quick search on the net I found this article, and it worked, now running Remote Desktop at the right speed.

In short
Here is what you need to do if you have the same issue:
- Run a command prompt (cmd.exe) as an Administrator
- Type: netsh interface tcp set global autotuninglevel=disabled
If you want to to re-enable it:
- Type: netsh interface tcp set global autotuninglevel=normal
In some cases you may need to use this command in addition to the above, but I didn't have to:
- Type: netsh interface tcp set global rss=disabled

bryanMaybe you have already encountered the strange behavior that it takes much longer to copy large files in Windows Vista than in Windows XP. You thought that the change from XP to Vista would at least be not a disadvantage speed wise but Vista somehow seems to have a problem copying large files. This happens especially with mapped drives but it could also be that you witness network disconnects.
The problem is caused by a new feature called Auto Tuning which is by default enabled in Microsoft Windows Vista. What Auto Tuning does is that it reacts on changes in the network by tuning the receive windows size. The solution would be of course to disable Auto Tuning in Vista. Some users reported that disabling Auto Tuning had a positive effect on their ability to connect to services such as Windows Live Messenger which did not work before.
To disable Auto Tuning and speed up the copy process and avoid timeouts and disconnects do the following:
Open a command prompt and type the following:
netsh int tcp set global autotuninglevel=disabled
To turn it on again:
netsh int tcp set global autotuninglevel=normal
Cancel some of Windows Vista Effects
Disabling some of Windows Vista’s Visual effect will make your Video Card and CPU very grateful. Do the following:
1. Open Control Panel.
2. Click on ‘System and Maintenance’.
3. Click “Performance Information and Tools”.
4. Click “Adjust Visual Effects”.
uncheck everything but :
Show shadows under menus Show shadows under mouse pointer
Show translucent selection rectangle
Show windows content while dragging
Smooth edges of screen fonts
Use drop shadows for icons labels on the desktop
Use visual styles on windows and buttons
Remove Tablet Feature

If your computer is not a Tablet Computer (most odds) go to Control Panel –> add/Remove and select remove system components uncheck Tablet PC since you don’t have one… For more advanced users you can change the Tablet option in the Services.
If you are serious about performance, you can also type out
Microsoft Xperf, just make sure you read the manual first.
