Transfer files to VIsta from XP

Hi all,

I have just got Vista Premium and am running XP Pro. I installed the lltd
on XP and for some reason I still cant see either machine when they are
shared out. I have other XP machines and can see the XP machines from my XP
boxes but cant see the Vista machine nor can the Vista machine see any of the
XP machines. I know this post has come up often but trying to figure out
what is wrong here.

I noticed someone posted about MSFT offering free support for Vista for new
computers. If someone has that # I dont mind calling them.

Thanks!
