Does RDP on Windows Vista encrypt credentials?

I bring my laptop with me when I travel and am concerned about security on "public" wifi's such as airport/hotel/resort when I want to use them to rdp into my business servers.  What is the risk of 'sniffers' or other users viewing my traffic on my wifi? In terms of key logging and especially sending credential when I launch the rdp client on windows vista and use the wifi to stay connected to my rdp server.  No I do not have a vpn setup.  What are my risks? and can the wifi node log all key presses?

Also I have heard of malicious schemes that involve users running wifi nodes with similar names to the public thereby confusing users into picking "Seattle Airport Public Wifi" vs "SEATWIFIPUB"(the real one in this example). Can anyone offer any thoughts on this?

Every version of RDP uses RSA Securitys RC4 cipher, a stream cipher designed to efficiently encrypt small amounts of varying size data. RC4 is designed for secure communications over networks, and is also used in protocols such as SSL, which encrypts traffic to and from secure Web sites.

The only risk is a vulnerability in RDP protocol or in the RDP CLIENT.

If you regularly update your system (automatic updates) I think your rdp connection credentials are safe.

as marcokrecic mentioned you need not be concerened about encryption so much providing you have the latest client.

However, the later part of your email mentions an issue of a sort of spoofing your server which is entirely possilbe (see link below). I highly recomment you utilize a certificate server to verify the identity of the server if you are concerned about that. You'll want to install the cert on your workstation once complete since you won't be able to validate the Certificate Server unless on VPN.
