Please Help. remote desktop conect to XP from Vista…Problems!

I just got a computer using Vista Premium and cannot seem to connect (via remote desktop connection) to my work computer which uses XP(server is Windows 2003 R2 standard edition). When I open the “Run” window I use “mstsc” (what I use for my other XP comptuer which works fine) and then put in all the correct info. I get a promt which says that “the remote computer is running a version of windows that is earler than windows vists.”

Can I connect to another computer, ie windows xp, via Vista Premium?

Any help will do. THank you in advance for any replys.
