I have a new PC running Vista Home Premium & a laptop with XP Home. I am
trying to set up a wireless network between the two. My problem is that the
PC can see and access the files on the laptop and the laptop sees the files
on the PC. However, despite allowing full access to the 2 hard drives on the
PC which are not password protected, I get the message "access denied" when
clicking on either from the laptop. Both computers are using the same
network name and the Norton firewall seems to be configured ok on both. Also
I can't access the printer connected to the PC which I could on my old PC
running XP. I have no problems accessing the Internet through the
router/modem on the laptop.
