here is the setup. My main computer, I just installed Win 7 Pro 64bit with 160GB HDD and a 1TB second HDD for storage (named "Main"). In my office I have a computer with XP Pro SP3. I can connect from Win 7 to XP no problem. When I try to go from XP to Win 7 I can connect to "user\public" no problem. I can see "Main" but when I click on it it says I don't have permission. On Win 7 I have passwords turned off in the network settings. I can't think of what else it could be. Any ideas?
