What editions of Windows Vista support Remote Desktop?

You can use any edition of Windows Vista to connect TO ANOTHER COMPUTER using Remote Desktop.

However, you must have Vista Business, Vista Enterprise, or Vista Ultimate in order to allow other computers to connect to YOUR COMPUTER using Remote Desktop.

For example, if you chose Vista Home Premium, you will be able to remote desktop to a computer at work from your home premium machine, but you WILL NOT be able to remote desktop to your home premium computer FROM WORK.

However, if you chose Vista Ultimate, you will be able to both remote dekstop to your work computer from home AND remote desktop to your home computer from work.
