Roaming profiles between Vista and XP

I'm having some serious issues getting roaming profiles to work between Vista
and XP. I've looked at this article from the Vista MVP site of how to use
roaming profiles between the two systems, but I'm not having any luck.

My desktop does not carry over and displays an error that I can't figure out
where the setting is comming from, something about not having permission for
the desktop and applicate data is not carrying over. There is nothing in my
quick lauch, where there should be icos is a big empty space and you can't
add anything to it.

The favorites work fine and it maps my network drives, expect it doesn't map
the home folder the way it use to in XP which is another issue.

Also the start menu carried over, but was extremely slow to the point it
would lock up for a few seconds.

Does anyone have any experience with this and can give me a hand and what is
wrong or what I should try? I am considering having different roaming
profiles for vista, but it would require more manual work and could lead to
docs not being saved, etc.

Could use some help here.

Thanks.

Hi Pete,
