Slow Remote Desktop Connection?

I have spent most of the last 9 months logged into my university PC from home using Microsoft's Remote Desktop Connection. It has been a life saver, but every now and then things go wrong. One of the most common problems I have is occasional days (such as today) where the connection speed is so ridiculously slow as to be unusable. This seriously hampers my productivity and I haven't been able to achieve much of anything over the last 4 hours.

The problem is not the internet connection at either end: running connection speed tests at both ends shows that both internet connections are normal and fast.

Doing a quick search on the web in frustration I just discovered a solution that seems to work. The details are discussed here, but it basically comes down to the new version of Remote Desktop Connection (6.0) using a feature called Receive Window Auto-Tuning. This sounds like a beneficial feature in general, but temporarily disabling this service speeds up the slow connection problem immediately. Here's how:

1. Disconnect from Remote Desktop.
2. Open an administrator command prompt and enter:
   netsh interface tcp set global autotuninglevel=disabled
3. Reconnect Remote Desktop.

When you're finished with the connection you can turn it back on by reversing the command:
netsh interface tcp set global autotuninglevel=normal

Somewhat tedious, but only occasionally is my connection afflicted, so I can handle it to regain lost hours of productivity. [TMCnet]
