Ref. the ending of security updates for XP: I have removed the Default Gateway entry on a Windows XP machine that I still want to have access to/from our small office LAN but do not want any access to/from the internet.
This seems to be working fine, In that, as far as I can tell, you can't access it from the internet (tried to access the computer via Logmein - used to be able to). Also the connections on the local network are working fine and you cannot view a webpage via Internet Explorer.
The PCs are all behind a router firewall and all have Norton Internet Security on.
Have I done enough to continue safely using the XP machine on the local network? Or is there still a risk?
