Windows Vista Beta 2 Public Download
This came online about 6 hours ago, so their servers are too busy to respond. Give it a few days once the excitement has died down.
Remember: Do not install this on a computer that is used for anything important. This is a Beta and by all counts has some issues.
The download is 3gb so its not a trivial.
