Microsoft recently release an updated version of their Remote Desktop Connection Client for Windows XP that supports the new Windows Vista features. The Remote Desktop Connection Client is used for connecting to a remote Windows computer running Remote Desktop or Windows Terminal Services. It is also used for remotely administering a Windows server that has this feature enabled.
The software includes new security features, such as it now prompts you to enter your username and password before logging on to a remote system. It then passes the credentials to the remote computer when it connects.
To download this software, check out Microsoft's KB article: 925876. This page includes links to download all versions of this application (including Windows 2003 Server, and the x86 and x64 versions).
