Can't access other computers on network

Hi!

I'll appreciate if someone can help me to resolve the
issue of not being able to access other computers sharing
files in my wireless network. I have tried using the
wizard "Setup or change your home or small office
network" but the wizard always gives an error messages
after begining with the auto setup process. I am running
XP Home in the computer connected close to the linksys
VPN broadband router, then one PC running XP
Professional, and a laptop running XP professional. I am
able to see from the PC-XP home the group icon in the
window explorer but then when I click to expand it but
gives me an error that says "Group not accesible. You
might not have permission to use this group network
resource. Contact the administrator of this server to
find out if you access permissions. The list of servers
for this group is not currently available." This is
stopping me for mapping the files and printers.

Thank in advance for any help.
