Here's a good Friday afternoon problem... Mrs E has got a new laptop with Windows 7. Our main machine is XP. We have been able to see the XP machine from the W7 machine (she's been able to pull music and work files across) but it's recently stopped. Fed up with the moaning I've had a look, searched through the net, etc, but can't for the life of me work out what's going on. I can see the XP box from the network map, but within "Computer" it shows the wireless printer, router, and the local W7 box (no XP box). I can ping W7 > XP and XP > W7 via IP address and name. Tried with firewalls on and off. W7 laptop: Set up for a work network, 128-bit encryption, password-protected sharing off. XP: Has simple file-sharing turned off (it's an XP Home machine, but followed the instructions on setting the properties within safe mode) I'm able to set up a mapped drive so she can get at the stuff she needs, but I'll be getting it in the neck (she's just come in and started already!!). AFAIK nothing has changed on the XP box, but it is possible that the moody teenager has mucked something up and is denying all knowledge. Any suggestions?
