from my w7 pc, when i go to network sharing center/see full map, i can see my xp pc's but not the shared folders on them, does anyone know what i can do?
have you enabled all the file sharing/printer sharing stuff on all PCs?
if you have done that then maybe windows is getting confused as to where to find it. you can make a shortcut directly to the shared folder by right clicking the desktop > new shortcut > then type the name of the folder with two slashes on from of the name(i would just put everything n the desktop for now).
xp sometimes doesn't find computers/folders though its automatic discovery tool, if you do it manually it is reliable.
i used the search box and put in the ip of the pc i was trying to access and got that error '//192.168.0.121/stuff' i put that in the search box on my w7 pc and got the error
