I have a new Sony VAIO w/ Windows 7. I'm trying to connect to a Vista 64 bit. I got the new Sony out of the box, put in my WEP key and away I went. I was able to map network drives between them both at first. Then I was messing around with adding/removing software & trying new locations for the router to get a better signal. I then was unable to map drives from my VAIO to the Vista. I could however map drives from my Vista to my VAIO. I kept trying different things, looked at all Mcafee settings on each & they all matched up. There is only slight diff in Windows 7 & Vista settings. I tried hardwiring & wireless to the Vista, wireless to the VAIO. I then tried a new Cisco N router, same thing. The Vista always shows up on my VAIO map, but the VAIO sometimes shows on the Vista. I'm sure it's a simple setting somewhere I'm missing, but I've looked everywhere. The drives on both computers are set for sharing with all permissions to everyone. Any Ideas?
