Windows 7: Cant see shared folders

from my Windows 7 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.

when i try that i get a 'class not registered' error, if i can see the pc why cant i see the shared folders on it?

dang i forgot to tell you that you need to put the name of the pc in there too. like this:

//name of pc/name of folder/name of file

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 Windows 7 pc and got the error
