attached: About Network Level Authentication (NLA)

Network Level Authentication is a new authentication method that completes user authentication before you establish a full Remote Desktop connection and the logon screen appears.

Network Level authentication has the following advantages:

• Initially it only requires a small amount of remote computer resources, because the remote computer uses only limited resources before authenticating the user. In earlier versions, the remote computer started a full Remote Desktop connection.
• It can help improve security by reducing the risk of denial-of-service attacks (denial-of-service attacks that attempt to limit or block access to the Internet).
• It uses remote computer authentication. This helps prevent users from connecting to remote computers that are established for malicious purposes.

To verify that the computer is running a Remote Desktop version that has network Level authentication, follow these steps:
1. Click Start, click All Programs, click Accessories, and then click Remote Desktop Connection.
2. Click the icon in the upper-left corner of the Remote Desktop Connection dialog box, and then click About.
3. Ensure that the word "Support Network Level Authentication" appears.
