A client of mine has a vista home basic PC and 2 XP Pro PC's. One of
the XP boxes houses the shared network files and the vista box has 3
mapped drives to the xp machine. the xp boxes are working ok.
Everything was ok but as of Friday the shares now have a red X over
them and I cannot access them with the vista box. I have internet on
all PC's, but I just can't access the shared drives with vista.
I have turned off the firewall (windows) and the antivirus (nod32) on
the vista machine and created a new share on the xp machine but still
cannot access the xp box from the vista.
I replaced the router just to see if it may have been the issue.

Any thoughts?
