I have a problem with HomeGroup on Windows 7. I connected laptop with Windows 7 Ultimate x86 and new computer with Windows 7 Ultimate x64 and I shared hard drives and libraries. And there is a problem when I tried to access files on new computer from laptop and vice versa, it sais: Cannot access COMPUTERNAME-PC, error code: 0x80070035. How to solve this problem? I need to transfer files from laptop to new computer via HomeGroup because I haven't Easy Transfer cable. Thanks.
