Vista Tutorial - Profiles

to reply by email please remove SPAM from the email address.
I have a problem with LOCAL profiles and Remote Desktop Connection.
I have seen this for quite sometime and thought it was a local profile
problem. or shadow copy error. Another Tech I work with has experienced the
same thing on his computer when using RDP.

I just got a new PC and installed Vista64 Ultimate on it, the user is a
network user with a local profile.
when logging into the PC remotely it loads a profile from "somewhere" with a
bunch of stuff, about 6 GB of data.
the desktop is one from about 4 months ago, including a "Vista ISO Image"
and Office 2007 ISO on the desktop.
the user does NOT use or have a roaming profile so every new PC login
"should" be clean.

question where do I remove this old information, how do I stop it from
happening again?
user is part of the ADmin group in a Win 2000/2003 domain.
The new PC has Vista 64 bit on it and the profile is from a 32 bit install.
Thanks in advance
