I need to know the exact smae thing. I get this when I am trying to connect to several XP pro boxes inside a remote network. I have disbaled the firewalls on all those xp machines and have properly forwarded to correct ports for each box through the router. I do not understand why i CANT connect to the xp machines yet I CAN connect to the 2k macheins.
I get the same thing you do :::
connection I/O error, connection may be closed due to IP Filter setting on the remote side
