ingenious code ::

After installing windows vista month (upgrade install) I encountered a weird problem with RDP. On some of sessions, the connection was very slow. The slow connection was not happening on a specific connection to a specific operating system, so I became really confused. After doing some research it seems that Vista enables TCP Window Scaling by default (disabled on XP by default).

So in order to disable it you need to run the following steps:

1. run command prompt as an administrator (right click on the command prompt)

2. run these two commands:

netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled
