Unable to login to BBC jobs web account

I have an account with bbc.co.uk/jobs. This site will no longer take my password but other computers will allow me access. In the Norton view history site it shows blocked traffic with info such as Default block EPMAP and Default block Microsoft Windows 2000 SMB. I've tried Norton Live chat - the person disabled Norton but the problem persisted. As this is the only web site on the net that I must access for work its a bit of a problem.

Any thoughts. With Norton 2008 this wasn't an issue.
