Is there an adminpak that will upgrade my current RDP so that I can remote into a Windows 7RC box?

I apologize for not providing spec's on my current XP box. I am currently running XP w/SP3. I've updated RDP TS client to 6.1.Both boxes are ona domain and my Win 7RC was configured to accept my user ID as a remote user. We do not have a Terminal Server in our environment. I can remote sucessfully with my Vista box but not my XP box.

Did you configure Windows 7 to accept Remote Desktop connections from computers running any version of Remote Desktop and not just from clients supporting Network Level Authentication?Windows XP does not support Network Level Authentication.Ray

Well what do you know. That was it. Once I changed that setting the world started to revolve again. Thank you for your suggestion.
