I turned off, xp firewall, disabled NAV, Norton Internet security is off. Ports are set correctly in OE. Something somewhere is blocking it on that pc, as I said I transfer the e-mail settings to my pc and downloaded all the mail no problem and that's behind mcafee firewall and a router.
I just don't seem to be able to find what's blocking it, apart from a format and reinstall not sure where else to look.
