I've just bought Time Capsule and set it as my iMac and Windows Notebooks at home can all connect to the internet. Both my Mac and PC are in the same Network (Workgroup). From my PC, I can see xxx'x public folder. When I enter the folder, there's another one inside: Drop Box. But when I click it I get this message: "\\mac...\xxx's public folder\Drop Box is not accessible. You might not have permission to use this network resource. Contact the administrator of the server to find out if you have access permissions". I've already enabled the SMB option under File Sharing. From my Mac, I can see my PC at that side column on Finder, but when I click on it, "connection failed" appears. If I click on the "connect as" button, comes the window: Enter your user name and password to access the file server xxx. Connect as: Guest - Registered User. If I connect as a guest, it fails. If I connect as a registered user, even if I use my pc user account credentials, it fails to connect.
