Outlook 2003 .pst problem w/network

I just replaced an xp computer with an xp media edition computer, and I added it to my peer to peer network. Everything works fine. I can access files on my new computer ... except for my outlook.pst file. When I direct my laptop computer to my main version of outlook it tells me I don't have authorization. This is weird because if I go to my network computers on my laptop and access my documents (which is where I have outlook.pst) I can open and access everything. Does anyone know why outlook.pst wouldn't be available when it is working and everything else is accessible? Please help.

 

I got it working. When I shared my documents I forgot to check the "allow other users to change my documents" box. So all is well.
