Help! I have 3 computers on my home network. I've enabled file and printer sharing on them and able to access all my computers from my windows 7. I can see all the computers in my network from each computer. I can access the files from my other computers (Windows XP & Windows Vista) on my Windows 7 computer. However, I cannot access the Windows 7 (i can see it from the other computers) from any of my computers. When I try to access the files I get an error message "Logon failure: the user has not granted the requested logon type at this computer".
