I reloaded, deleted the internet temp files, relaxed the IE security settings, switched off the firewall, tried Firefox, installed Java etc. Browsing the internet and getting into other secure sites is no problem.
Holistically my laptop works on our company lan but at home it does not. I am sure my adsl modem is not filtering or anything as it's a plain vanilla. The only difference really is the ISP....does the login use some port that is blocked by my ISP. It has to be ISP related me thinks!
