Networking issues with Vista Home Premium and Vista Business

Hi Everybody!

I have a problem I'm hoping some one could shed some light on.

I have been attempting to network 3 computers, 2 using Vista Business
and 1 using Vista Home Premuim. I have added a common user to all
computers, created a folder and set premission for the common user to
have access to that folder, this is so they are able to access shared
folders on each others computers. The problem is that the Home edition
can not be accessed from the other Business edition computers. But
there is no problem for the business edition users to access each
others folder but they are unable to even see the home edition
computer...

I hope that makes sense!

Any thoughts?
