I backed up heaps of files from a Vista system to an XP Pro system on the same network. Then I deleted everything on the hard disk where the Vista was and installed Windows 7. I had problems when I copied the files back from the XP to Windows 7. The process could take one to two hours. The problem was not the length of time it took but loss of communications. It seemed to be fine when I initiated the process at Windows 7. However the communications was lost every now and then if I initiated the process at the XP side. When it happened I couldn’t even access the Windows 7 computer from the XP system and I needed to restarted the XP system to recover the communications. I forgot to check if I could access the XP system from the Windows 7 system at that time. I doubt I could though.
It appeared to me there was a difference in communications between Windows 7 computers and mixed systems. It performed less satisfactory with the latter.
