You need to provide more info to get help. Can the other machines see the XP machine under networks but can't connect, or are they not seen? Are you using simple file sharing on XP or regular sharing with user names and passwords? Have you enabled file and printer sharing in the TCP/IP properties of the network connection on XP?
We just got a Win 8 machine, and finally decided to make a workgroup to share printers. made the workgroup, named workgroup, on the new win8 box. two desktops with win7 connected perfectly.
I cannot get the xp laptop to connect, I changed the Name from mshome to workgroup, but it still does not work.
Any help would be appreciated
