If so, what have you changed, and you might try a System Restore. If not, do both the comuters have the same network name?
I have a wired desktop (XP Home, IE 7)and a wireless Laptop (XP Home, IE 7) via a Linksys router and a DSL high speed modem. The file folders I have checked to share on the laptop does not show up on desktop when I open My Network Places. The ones I have shared on desktop does show up on laptop in My Network Places. If I click View Network Computers on either machine, both computers show up. The connections are good and I can get on internet on either PC. Why are the shared files on laptop not showing on desktop.
