I have alaptop connected to my desktop with a ethernet cable. The destop can access files from the laptop but no traffic the other way. I have now connected the laptop to another desktop and it works fine both ways. I have tried lots of things like taking off all firewalls, permisions etc. The laptop is OK the cable is OK. Something on the first deskktop is stopping access could it be updated software from ms xp all pc`s are running xp
