I have 2 computers, one hard wired (call that PC1), and a wireless workstation (PC2). The wireless is configured with WPA-PSK security and is working fine. PC1 has a hidden shared folder setup for access from PC2. I have customers who visit regularly and need internet access during their visit; and I provide them with the passkey (which I change on a monthly basis), but I'm worried about them gaining access to the data, even though I've setup the shared name with a dollar appended to it. I have had no success in assigning a password to the shared folder.
The main question is; what's the safest way for me to have a wireless environment, but ensure my customers will have no possible way of gaining access to my data. All it would take is a tool to scan for hidden folders on a local network to get into the wrong hands.
PC1 is a Windows XP Home desktop.
Thanks in advance for your suggestions.
