Step 3.  Choose the level of security and who can connect

a) Select Allow connections from computers running any version of Remote Desktop to allow people using any version of Remote Desktop or RemoteApp to connect to your computer. This is a good choice if you don’t know the version of Remote Desktop Connection that other people are using, but it is less secure than the option b).

b) Select Allow connections only from computers running Remote Desktop with Network Level Authentication to allow people with computers running versions of Remote Desktop or RemoteApp with Network Level Authentication to connect to your computer. This is the most secure choice if you know that the people who will connect to your computer are running Windows 7 on their computers. (In Windows 7, Remote Desktop uses Network Level Authentication.)
